How to find the Lowest Common Multiple (LCM) #6

This video covers how to find the "Lowest Common Multiple" of a group of numbers. We cover 2 methods. The first is the easier method, which involves listing out the multiples of each number and picking the lowest multiple in common. The second involves using the prime factors.
This video is suitable for maths courses around the world.

[@saniya_Amira_25]

your all video helps me in getting an explanation

[@tonyzambonistarkoni7868]

One method you could use to find LCM's is to put all the factors into a venn diagram, with the factors present in both numbers in the overlap. To find the LCM, you multiply all the numbers in the venn diagram (not the same as multiplying the original numbers together because if 2 is a factor in both, it only appears once in the overlap.) To find the HCF, you multiply the numbers in the overlap.

Thanks alot this helped

So if you have to find the lowest common multiple of 6 and 9 it would be 3x3x3x3 and what your saying is to count one of them so it would just be 3x and nothing else to multiply it with
