First year college student here, majoring in CS and I slacked off in math throughout school. This channel is helping me catch up so much its a lifesaver
I am happy to help out the next generation. This trick was casually mentioned in one of my college classes and I remember thinking how I wish I had this back in the day. I wish your the 10 year old the best with this new trick!
LOVE this TRICK!!! I had some GREAT math teachers growing up but can we just clone you across the US bc these math teachers in the NW are dry and boring and they’re trying to reinvent the wheel! Stop making math so difficult for our kids! Just teach to reach! Thank you for this, I’ll pass it along to my boys.
I found this technique in a college combinatorics textbook. It was mentioned somewhat casually but I thought it was very interesting. I remember thinking that this topic should be taught in every elementary school!
this probably won't get answered, but why 1? why add 1 to the exponent to come to the conclusion with how many factors total there are for the given number? I also got lost at the trick but I understood it through. just, why the 1??
This trick is an application of the multiplication principle from combinatorics. This is the same concept as "Vin has 4 different T-shirts and 3 different pairs of pants. How many outfits can he make? Ans: 4*3 = 12" For this number trick, let's use 12 as an example. 12 = 2^2 * 3^1, so there are (2+1)(1+1) = 6 factors of 12. Any factor is built up of a combination of a 2 or a 3 (similar to a t-shirt and pants from the last example). However, for one of the factors involving 2, we could use 2^0, 2^1 or 2^2; that exponent 0 case adds one extra potential choice for each factor, that is why we add 1. For 3, there is 3^0 or 3^1, so there are two choices for the factor involving 3. The first factor 1, should be thought of as 1 = 2^0 3^0, and 12 can thought of as 12 = 2^2 3^1. This is a tricky concept to type, but I hope this explanation helps!
It works, I promise! The prime factorization of 100 is 2^2 5^2, the exponents are {2,2}, add one to each exponent and multiply, you get 3*3=9. So 100 has 9 factors. The 9 factors of 100 are {1,2,4,5,10,20,25,50,100}
Thank you so much sir, this was immensely useful for me. Even as a 12th grader taking Maths, I never actually thought there was a way where you could find all factors of a number, but I had to learn. And no video on TH-cam was as clear as yours, not only that, but also, very easy to do. Unlike these complex methods on TH-cam I found that I honestly could not understand at all or memorize. But this, this is it! Thank you again. (This would've been so useful to learn when I was younger, too. But at least I know now. )
Please help! As stated in another comment, this does not work for #36 (or at least I think it doesnt). The trick tells me that there should be 9 factors when I can find 10. Please explain if and where I am going wrong
Joycinha Borges The 9 factors of 36 are 1,2,3,4,6,9,12,18, 36 Six shows up twice put we only count it once when we list all the factors. Factors will repeat with all perfect square numbers.
100 = 2^2 5^2, so take the exponents, add one and multiply: (2+1)(2+1) = 9, so there are 9 factors of 100. The factors are {1,2,4,5,10,20,25,50,100}. Perfect squares can be tricky because they will tempt you to count the repeating factors twice. When people encounter 10x10=100, they want to list 10 twice, but only list it once.
We all are sinners and we must get punished for all of our sins by spending eternity in hell but Christ loves us so much he took the penalty for all of our sins instead by dying on the cross. On the third day God raised Christ our Lord, King and Savior back from the dead. If you already believe this and you are a believer of Christ, share this good news and don't be ashamed or lazy to do it because people still go to hell for not believing in Christ as their Savior and Lord
This trick for counting the factors needs to make it into the US schools! I learned how to prove that trick in college and remember thinking that it would be so useful for 5th grade. Good luck with your schooling!
I think it is time to upgrade this video and go through more examples. I will make sure to outline the steps more clearly in the new video. Thanks for watching and commenting!
Glad you think so! I remember learning this counting factors technique in a college math class and thinking this would be great to learn in the earlier grade levels.
Hey man , well it seems i struggle with your trick i think you should have done a bit more examples in 2:22 because of noobs like me so anyways :P Factors of 28 so 28 then 14 x 2 prime is 2 so we continue with 14 2x7 is 14 then we bring down the 2 so what's left is : 2 x 7 x 2 Now referring to your trick the first 2 has 1 exponent then 7 has 1 exponent then again number 2 has 1 exponent right? What is wrong in this line because then i add 2x2x2 and is 8 but the factors of 28 is not 8 but 6 so any help is appreciated.
You need to group the 2s: (2x2) x 7 = 28 The 2 has an exponent of 2 and the 7 has an exponent of 1, so it becomes 3 x 2 = 6 The 6 factors are then 1, 2, 4, 7, 14, 28.
you used to be my old math teacher in CSI back in like 2018-2019 you were mad cool and would always tell us to watch the ads I don't think this video had nowhere near this many views at the time. good luck bro and keep it up
Great to hear from you and I appreciate your kind words, Anthony! I enjoyed that time at CSI, I can't believe how fast the years are going. What career path did you choose?!

I am happy to help! I appreciate you supporting my old videos!
Hello other struggling math students
The struggle is part of the game! That means you care.
@@vinteachesmath Thank you! This video helped out a lot as well
That's an amazing trick. I'm going to show this to my son, hopefully it will help him. Thanks for posting it.
Good luck to him and thanks for watching!
@@vinteachesmath oo
@@vinteachesmath good luck your channel will improve
Love your accent! Are you from Jersey or PA? Great video it really helped me understand.
NY! I'm glad you liked this video. I wish I knew this technique back in 5th grade
That is exceptionally cool! I had no idea - thanks for sharing :)
😎
thanks man now im a pro 😎you earned a sub 😎😎😎😎😎😎😎😎
Thanks for the sub and the emojis!
Thx for this trick it helped me win a math competition
Congratulations on winning the math competition! That is a huge accomplishment! I am glad this trick was useful.
This was really helpful. Appreciate your help.
@santassurprise7614 glad it was helpful! I hope your school year is going well
Thank you so much dude because I take a long time listing factors and miss the sneaky ones so this video will benefit me a lot :)
Glad it helped!
this guy needs better quality and the marker is annoying. but the vid is helpful
This is a game changer for my 10yr old :)

OMG it actually works,my maths exam is tomorrow and i am always confused in finding the factors of 216,Oh My Gosh!!!!, Thank you so so so much 😊😃
Glad it helped! Thanks for supporting my first generation videos!
Very cool... I did get lost on the explanation of “The Trick”
Wonderful explanation, sir. Is there a name for the 'trick' formula, so I can look up how it's derived?
I found this technique in a college combinatorics textbook. It was mentioned somewhat casually but I thought it was very interesting. I remember thinking that this topic should be taught in every elementary school!
This was a lifesaver. The first video I found that gives me a method that makes sense. Well explained. Thank you.
Glad it helped!
Now this was one amazing and clear video that helped my problems. Thank you for your help.
Glad it helped! Best wishes with the rest of your school year!
Thank you after watching this video I clear prime factors concept.
Glad it helped and thanks for supporting one of my original videos!

The first factor 1, should be thought of as 1 = 2^0 3^0, and 12 can thought of as 12 = 2^2 3^1.
This is a tricky concept to type, but I hope this explanation helps!
Thanks my baby
.
Sir salute you, I have my exams on 12th October, please wish me luck🤞🍀
Good luck! I hope your exams go well!
In my school they call it the factor tree method
I don't really get the trick. How did you get 2 times 3 times 2 from those exponents?
He added 1 to each of them
So interesting that math works like that sometimes. Best method I've found, thank you!
Superr math trick
Well done ,keep going.Your video was very helpful .you are best
Glad it helped!
wtf blad, so FUCKIN AWESOME!!!!!! :>D -.- :) :D D: :3 :P ;(........XD XD XD XD GD *GOOD LUCK*
#POSTNOTIFICATION ON
I have always struggled with factoring numbers lol, but this trick has really helped!! Thank you so much :)
Happy to help! I love this trick! This should be shown in every elementary school! I wish I knew it sooner!
This is not a proven solution. I tried it with 100 and the trick is flawed.
It works, I promise!
The prime factorization of 100 is 2^2 5^2, the exponents are {2,2}, add one to each exponent and multiply, you get 3*3=9. So 100 has 9 factors.
The 9 factors of 100 are {1,2,4,5,10,20,25,50,100}

I am very happy to hear that this was so useful! I learned this trick in my last year of college and would have loved to learn this trick earlier!
I swear your from brooklyn😂
Not an accent expert but, I guess he could also be from North Carolina, Georgia, or somewhere south. Not too south like Florida, somewhere between.
cool bro
Thanks for the clear lesson.
Glad it was helpful! Thank you for supporting one of my oldest videos. I hope your school year is going well.
cool math:)
Glad you think so! I love this trick!
This trick is so wonderful
Thanks very much for sharing this trick
Glad you think so! I remember learning this in college and thinking it should be taught as early as possible!
I love you
Trick is very good. It gives different approach
I love this trick! Thanks for watching.
Great 👍
Glad you think so!
Love this!! But I tried this method with the number 48 and it said 18 but I only got 10 factors? I don't know if something wrong or I messed up..
48 = 2^4 * 3^1.. So do (4+1)*(1+1).. Then there are 10 factors of 48.
I’m doing a math question asking me how many factors in the factor set of 350769078, and holy this didn’t help lol
There might be a prime factorization calculator for big numbers. Doing that by hand would be painful LOL.
Please tell in hindi sir 🙏🙏🙏
Thanks mate! That was really helpful.
Glad it helped! I love this trick, it still blows my mind.
THIS IS SOO HELPFUL AND I HAVE A FINAL MATH EXAM COMING UP!!!
How did the final go?!
@@vinteachesmath GREAT!!
Cool
Glad you think so! I wish I had this trick back in the day, being able to count all of the factors ahead of time would have been very helpful!
Thank you for this amazing technique. It's so enlightening. Can you do some videos on LCMs and GCFs, please.
Thank You Very Much Sir for putting such informative video. May God Bless you so much happiness and knowledge!!!
Shit u did great man you save my valuable tears
LOL, glad it helped!
Thank you

Please help! As stated in another comment, this does not work for #36 (or at least I think it doesnt). The trick tells me that there should be 9 factors when I can find 10. Please explain if and where I am going wrong
Joycinha Borges
The 9 factors of 36 are 1,2,3,4,6,9,12,18, 36
Six shows up twice put we only count it once when we list all the factors. Factors will repeat with all perfect square numbers.
vinteachesmath thank you. Yes I finally worked it out when I counted the facrors and when I counted 6 twice!
VERY COOL TRICK SIR! THANKS FOR SHARING THE TRICK. GOD BLESSES YOU ALWAYS FOR HAVING A KIND-HELPFUL-MIND!
I am glad you appreciate the trick! This needs to be in every elementary and middle school!
Super Cool Trick
Nice one i like it so much Thank You!!!!!!!!!
I'm glad you like it!
Can u try it by 729?
PL
After multiple professors and TH-cam videos, this is the first technique and explanation I have finally been able to understand and use. Thaaaank you!
super good method
Extreamly.. Hyperbolically.. Thermodynamically.. Helpful.. 😶😋😁
You saved my day 🙂Thnq....
Happy to help!
It won't work in 100 I tried many times
100 = 2^2 5^2, so take the exponents, add one and multiply: (2+1)(2+1) = 9, so there are 9 factors of 100.
The factors are {1,2,4,5,10,20,25,50,100}. Perfect squares can be tricky because they will tempt you to count the repeating factors twice. When people encounter 10x10=100, they want to list 10 twice, but only list it once.
Thx bro
Guy u rock ❤
Thanks! I made this video so long ago but I still love this trick!
Thats a key right there
amazing educator much thanks
Glad you think so!

The process is the same, although it will take longer as the numbers increase in value. Unless you pick a prime number!
trick name is LCM haahaha

boring need to bring the excitment
yes it does
Thx so much it helped😊
Glad it helped! I love this trick.
pretty good tip
Non of the vid is helping me with my homework. My teacher use to multiply the prime numbers in a radical symbol, so can someone help me plz
This didn’t work for me with 3235 it says I should have 16 pairs and there’s only 4 pairs?
wow
Thanku so much sir.
This is incredible
I love this trick! Thanks for supporting one of my older videos!
Thank you 😊 bro 👍 it did really help me
Welcome 😊
@@vinteachesmath will you please share us tricks on cube root and square root
That's fantastic! Thanks a lot for this video!
Glad you liked it!
Hey man , well it seems i struggle with your trick i think you should have done a bit more examples in 2:22 because of noobs like me so anyways :P
Factors of 28
so
28
then 14 x 2
prime is 2 so we continue with 14
2x7 is 14 then we bring down the 2 so what's left is :
2 x 7 x 2
Now referring to your trick
the first 2 has 1 exponent then 7 has 1 exponent then again number 2 has 1 exponent right?
What is wrong in this line because then i add 2x2x2 and is 8 but the factors of 28 is not 8 but 6
so any help is appreciated.
You need to group the 2s:
(2x2) x 7 = 28
The 2 has an exponent of 2 and the 7 has an exponent of 1, so it becomes 3 x 2 = 6
The 6 factors are then 1, 2, 4, 7, 14, 28.
Nice and clear Good job! 👍
2:00 Can someone please explain why this trick works this way? Thanks.
Thank you so much
You're most welcome!
