Edit: Pause at 0:00
Actually sir enjoys teaching
😂😂😂😂
😂😂😂
Good, though the only negative is you will have to somehow learn your time-tables quickly and mentally be able to calculate them immediately ( I mastered it a long time ago) but other than that I think its a pretty good solution.
Sir what if there are 2 no. not divisible by highest no.
same question i wanna ask
Give me the numbers

Sir this is VASTAV MAHANT of class 8.My board is ICSE.Ur explanation is great and simple.Pls keep going on making vedios.
I knew that .... I had been using this since fourth standard ....... but I did not know it was a trick .....I thought it was a common logic that everyone knew about and used
Thank u... Sir.. Great and fine presentation 😍
One thing i want to mention that...
While finding LCM...
WHEN we go for next multiple of highest no.... When two other no.. Are not multiple of highest no... Then after finding 1st number's multiple, when you meed to find next numbers multiple, u need to take multiple of,which no. You selected for 1st number.. And not of original highest no.
E. G.. Lcm of 40,50,60...??
Take 10 as default and multiply it by the LCM of 4, 5 and 6
Thank you sir ... For spending your valuable time and it was a great class ... Waiting for your next classes ... great 🙏
Why are Asian math teachers so smart?
I learned so much thank you
Extremely useful! Thank you!
+Naida Taylor....Thank You. ....keep viewing and keep sharing.
Thank u sir, for helping me. Hope you can give us more videos : )
Thank u sir. I can understand easily now
Sir all numbers are multiple of 50 is a wrong statement. Correct statement is ALL THE NUMBERS ARE FACTORS OF 50. You said that when prime number left with the highest number then no need of taking LCM just multiply the both numbers. But I think when the highest number is the multiple of prime there is no need to multiplication. Regards Surendra Singh , Maths teacher
+The Maths Guru.....agree to first part (was just an error) but not to second part
Amazing sir!!Even I teach maths on my channel and I just really love your videos and tricks
This is good to combine (in a way) with the ladder method. Meaning that if that if the rule applies, as in your first example, you can just avoid doing any other steps.
Very nice teacher
these r very hepful for competitive exam....thanq sir...
The most understandable explanation!!!
Thanks for your efforts sir, I know why Fans are off in your room and you are just sweating there, So that video won't catch extra noise . 🙏😀

If all the digits are not multiple what will we do at that time.
+Manjesh kumar....for coprime numbers the LCM is their product
If there are three co prime numbers,then what is the hcf of those numbers
It would be really helpful if you leave some questions in the end for us to solve and then you can explain how to do that, so we can see whether we really understand the method
Today I Know the very short trick... thanks sir
Amazing, helpful, thanks sur
you'd need a really strong multiplication table knowledge to pull this off
Come on, it's just basic multiplication🥴

very very helpful videos thanks sir
Thanks for thus special information
Thank you very much, Sir!! Sir, when I applied the same method for calculating the LCM of 2,4,6,8,10 and 12, I got the answer as 60. But, the correct answer is 120. 12 is a multiple of 2,4, and 6, but not of 8 and 10. So, 12*2=24, 8 divides 24 by 3. But, 24 is not a multiple of 10. Therefore, 12*5=60, 10 divides 60 by 6. Hence, according to the methods taught in the video, 60 has to be the LCM. Could you please mention the correct solution for this sum, Sir?
Pl sir explaine this
Sir please tell me the LCM of 63,70,77 by this trick with explanation.
Ok so we can clearly see that they are all a multiple of 7.
So what we would do is :
7( 9:10 : 11)
We put 7 in the LCM and we also know that 11 is a prime number
So we would multiply it all to get the product.
7x9x10x11= 6930
The answer is 6930
This method is easy and simple and quick and the best
Any pwian here🙂💗..
Thank you sir....
It helps me in physics.
i just realized nobody said bad things for dis #first time ever for me.
it os a gud mthod....but...dis trick doent work wid this given question......lcm of 24,36,44,62..?? please find d solution...nd reply me as soon as possible
hello " anjali mishraa" do u find the answer which was u mention in the comment?? really it contain some kind of difficult while doing big numbers... if u find any trick plz inform me dude
according to sir's method,
step 1:search for prime numbers in the given numbers
there is 11 in 44 , and 31 in 62 . so 11*31 will be the part of LCM anyway!
step 2: look for the biggest number apart from 11,31
we have 24,36,2,4
cancel 2,4 as they divide the biggest number,36
check: is 24 divides 36? no!
now,36*2=72, and24 divides 72 perfectly.
therefore, LCM=72*11*31
hope it helps!
@@shaikgouse770 my way of finding lcm to this question is
2^3*3^2*11*31=8*9*11*31
(8 in 24,9 in 36,11 in 44, 31 in 62)
method: multiplication of the highest powers of all prime factors!
@@mounikabhupathi2012 tqq u dude
For large numbers 1.write them in standard form.
2. Write down all prime numbers .
3. Raise their highest power.
4. Multiply them.. resultant product will be the LCM.
Thank you so much sir
life saver thanks a lot may god bess you
