Could have been spared a lot of heartache if my teacher would've just done it this way. I love your videos. So far they've helped me more than any other video out there. Quick, simple, to the point, no bs in the middle. Love it! Thank you!
Thank you so much for this video! I am a middle-aged woman and have not even thought of a lot of math I learned in school. Now that I will be becoming a classroom assistant, I need to brush up on things. I certainly wish we had tutorials like this when I was in school. Math might not have been so terrifying to me!
I'm in a programming class and I have to write a program for finding the gcf and reducing a fraction. You just saved me a couple hundred lines of convoluted code!
Thank you so much. I'm trying to pass a beginner college algebra course and have no clue what I'm doing. This is so much faster than trying to check every single prime number individually
Wonderful method. It was just today that one of my students asked me if there is a short cut to finding the GCF. I showed them the Ladder method. I do believe this method has that one beat! Thanks so much!
I've always struggled with Math, like so many others. I'm trying to get better, and your video just taught me in such an easily understood way. Cheers!
Wow, you really saved me a headache of worry and anxiety over these large fractions. I’ve been looking for quick solutions on these forever. You’ve just made studying so much easier for me. This will change my life! Thank you, so so much for the tip!
even though its been 7 yrs this actually worked, tysm i did it to find the hcf for 1126 and 9720, i thought it was impossible without spending like 30 minutes but i did it in like 10 minutes with your method, tysm!
I have a minor case of math dyslexia that has always prevented me from just seeing numbers in my head. This just helped me in such an immense way that I'm excited to do math again! Thank you for solving a 9 year struggle in 8 minutes!
If you could show how to get the LCF and how to do a math problem with 3 GCF and 3 LCF thagmt would be so helpful! You're awesome, thank you for your help!.
Thank you so much I was learn how to find the gcf and I got confused of how to do it but when I came to watch your video it help me so much so thank you so much and hope your having a great day 5:25
I take that back. I'll send you this word document. PPPLLLLLEEEEEEEEAAAAAAAASSSSSSSSSEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! explain why the GCF of 128 & 156 is 4, not 2.
Oh oh!! The Euclidean algorithm!!! 😁😁😁 It's the second fastest algorithm if you're concerned with integers in computers.... the fastest is Binary GCD algorithm. But it's good enough for us. Well done!👍
There might be a catch when you try this and the number on the right happens to be larger than the one on the left. Here's a graphical representation of how to deal with such problem: Find the GCF of 702 and 507. 702 - 507 = 195 (subtract and shift the last two down) ↓ ↓ 507 - 195 = 312 (same thing again, but notice that the difference is bigger than the subtrahend) ↓ ˢʷᶦᵗᶜʰ ↓ 312 - 195 = 117 (for this reason, simply switch them and subtract them as before) ↓ ↓ 195 - 117 = 78 (now it's normal again, so subtract and shift down) ↓ ↓ 117 - 78 = 39 (now you can probably tell that 39 goes into 78 two times, so 39 is the GCF) If you have problems reading this (I used a lot of special characters to format this), then tell me, I will give you the raw version.
***** Well, you need to calculate the modulo, so if the smaller number fits into the larger one no more than once, then you can subtract them. In other cases, you have to divide and find a remainder.
What happens when the smaller number exceeds the bigger number amount? Like when it can’t go into the bigger number even once? For example 250 and 130. 130•2=260.
Everyone should up vote this so it would have turned up search results sooner. Hands down the fastest way. BUT it is also impoyto do it with prime numbers so you understand the many uses of primes.
here is the best method i found for 3 numbers so far i hope its good for u too mathchat.me/2015/03/26/how-to-find-the-gcf-of-3-numbers-fast-no-prime-factorizing/
Great! In other words, THIS IS HOW TO SIMPLIFY FRACTIONS THE EASIEST WAY: If the difference between the numerator and denominator is 1, the fraction cannot be simplified. A. Ask: does the numerator go into the denominator evenly (i.e. without any remainder)? If yes, proceed to B. If not, proceed to C. B. Great! The simplest fraction is 1 over the number of times the numerator fits in the denominator. (e.g. 20/60, 20 fits evenly 3 times, hence 1/3.) C. Write the remainder, (e.g. 20/46, (20 fits 2 times in 46, with a remainder of) 6.) to the right of the fraction, and ask: does the remainder go evenly into the numerator? If yes, proceed to D. If not, proceed to E. D. Great! The "remainder" is the Greatest Common Factor. Divide both the numerator and denominator by the GCF/remainder to have the simplest fraction. E. Write the "new remainder" (using the last example, 20/46, 6 fits into 20 with a "new remainder" of 2) to the right of the previous "remainder", and ask: does the "new remainder" fit evenly into the previous "remainder" (2 into 6)? If yes, proceed to D. If not, proceed to E.
I had a problem with this one. The two numbers are 750 and 180, which give 4 r 16 carried over, then 180 and 12 with 11 r 25, but then it gives 16 divided by 25 giving 0.44. Help!
How are you getting these remainders? My calculator came up with different remainders for every example you've given. Even rounding the remainder didn't make it consistent to your...help?
This is a really late comment, but to get a remainder, the work has to be on paper. Only then will you get your answer. The calculator only comes out as a decimal, which is probably confusing you.

with this newfound knowledge i shall take over THE WORLD!!!!!(that is my math class)😁👍👍👍
😂
Hahaha
Did u do it ?
Did you do it
its been 7y how you been?
I'm in a programming class and I have to write a program for finding the gcf and reducing a fraction. You just saved me a couple hundred lines of convoluted code!
That is awesome! Hope the code goes well.

I was stressing out before I watched this. I knew there must be an easy way to understand this topic. Thank you so so much! Amazing!!!
love it - my kids are in 5th grade and have just started needing HCF (Highest Common Factor) I will be showing them this. thank you very much
thank you for saving me so much pain doing this
thank you so much this is the best tutorial in finding gcf i've ever found.
OMG U BLEW MY MIND THIS WORKS 100% I WAS DOING MY HOMEWORK AND IM ........ OMG

Thanks for the video, this is a much easier method to understand then the one in class. I get this one, the other was way too confusing.
Just found out about this because my little brother asked for help to do his homework, thanks my g!
Thanks bro your a legend I have a test tommorow
This is the best trick in middle school ever!
Thank you for sharing your knowledge.
It is the most simple way for GCF!
even though its been 7 yrs this actually worked, tysm i did it to find the hcf for 1126 and 9720, i thought it was impossible without spending like 30 minutes but i did it in like 10 minutes with your method, tysm!
Amazing method - makes simplifying ratios insanely easy
Math teacher told she gonna give us a hard activity tommorow,thanks for this bro.
Thank you so muchhh my math teacher is very unhelpful and you just taught me In like 15 minutes while she had 3 lessons and couldn't
Thank You. This method solved a big issue i have been having.
Ahh, the beautiful Euclidean algorithm. Thank you so much for this.
I have a minor case of math dyslexia that has always prevented me from just seeing numbers in my head. This just helped me in such an immense way that I'm excited to do math again! Thank you for solving a 9 year struggle in 8 minutes!
No You don’t just have to pay attention 😂
@@ILOVECHICKEN698 bro he probs does have dyslexia, it does mean he can't concentrate that well.
You made that so simple. Thank you so much 😊 I need your vids in my life 😆
You're good at math and, also a great teacher
Most teachers at math are meh, HAHA
I am truely so grateful for you. I hope all your dreams come true
i am glad i watched this video. really deserved more views .
Thank You! It helped me a lot. I usuallybhave really trouble in solving the gcf. Even if i ask someone they tell me the long process way.😅
Best method I've seen! Thank you
Thanks alot even tho im 6 years late this really helped me
THANK YOUUUUUU!!!!!!
This helped me so much with finding greatest common factors!!!1!1!1!!!1!🎉🎉🎉🎉🎉🎉🎉
If you could show how to get the LCF and how to do a math problem with 3 GCF and 3 LCF thagmt would be so helpful! You're awesome, thank you for your help!.
There is no such thing as a LCF because everytime it will be 1, so do you mean the LCM?
Wow thanks for this! I had 816 and 672 and got GCF 48! (144, 96, 48)
Thank you so much I was learn how to find the gcf and I got confused of how to do it but when I came to watch your video it help me so much so thank you so much and hope your having a great day 5:25
THANK YOU SO MUCH YOU JUST SAVED MY LIFE
Recently, I got an F for flunking a math test by Mrs. Irby about GCFs. This helped me a lot. If I can memorize it, I can go from an F to a B.
I take that back. I'll send you this word document. PPPLLLLLEEEEEEEEAAAAAAAASSSSSSSSSEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! explain why the GCF of 128 & 156 is 4, not 2.
Best explanation of Hcf
Thank you for your knowledge!
Bruh, you're the man! (Drop the mic)
This man is a genius
youre literally a genius
THANK YOU SOOOOOO MUCHHHHH OH MY GOD YOU MADE MY LIFE SO MUCH EASIER
Oh oh!! The Euclidean algorithm!!! 😁😁😁 It's the second fastest algorithm if you're concerned with integers in computers.... the fastest is Binary GCD algorithm. But it's good enough for us. Well done!👍
Subhomoy Haldar how do u do that?
YOU EARNED YOURSELF A SUBSCRIBER
This will help me greatly thank you.
my mind was blown haha thank you so much
Super easy man thank you!
Thank you so much, needed this for surds
The Euclidian Algorithm! Nice!
lots of thank you for this tutorial!
Love your accent and your videos!!
This is a more easier method than the ones they taught me in school and it's a way better approach to doing bigger numbers
you have saved my life
OMG TYSM IT MAKES IT SO EASY NOW!!!!!!!!!!!!!❤❤

Here's a graphical representation of how to deal with such problem:
Find the GCF of 702 and 507.
702 - 507 = 195 (subtract and shift the last two down)

507 - 195 = 312 (same thing again, but notice that the difference is bigger than the subtrahend)
↓ ˢʷᶦᵗᶜʰ ↓
312 - 195 = 117 (for this reason, simply switch them and subtract them as before)

195 - 117 = 78 (now it's normal again, so subtract and shift down)
↓ ↓
117 - 78 = 39 (now you can probably tell that 39 goes into 78 two times, so 39 is the GCF)

***** Well, you need to calculate the modulo, so if the smaller number fits into the larger one no more than once, then you can subtract them. In other cases, you have to divide and find a remainder.
Yes, but since 195 can be divided in to 507 more than once you have to divide. I don’t know why you subtracted
@@Tsskyx just realized I’m replying to a 5 year old comment
so simple, great video
Y do you stop putting out videos bro y I learned so much since I started watching your videos thanks a lot my brother
Khan academy killed him
@@61subsandnovideos huh
This was incredibly helpful
This guy has a really nice voice
Thankyou so much sir!❤❤
How would you get the GCF of 3 or more numbers?
What happens when the smaller number exceeds the bigger number amount? Like when it can’t go into the bigger number even once? For example 250 and 130. 130•2=260.
Thx for sharing this method, really useful
Thank you i learned from you
tysm helped me ALOT
Thank you so much for ur help!!!
This is so helpful!

What kind of sorcery is this?! Haha thank you soooo much ❤️
Cheers mate
This is brilliant!!!
this helped me a lot
thank you so much it will help me a lot
How did you get a remainder of 60?
This is very helpful
So helpful, thanks!
Thanks I’m in 6th grade 😊😂😂
Does this work for 3 numbers?

I got 750 180 4r30, 180 30 6NR, The answer is 30. Check your math.
i miss online class when i was actually still determined to study cause it used to be fun
Thank you so much
what if the number is smaller than your answer
30 minutes till my quarter exam and Im here for knowledge
Hiii!, can I ask if u can do an gcf example,just for our exam.
