Example: 30 and 42
Factor them.
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the highest amount of each factor.
2 x 3 x 5 x 7 = 210, the LCM
Multiples of 210 will all be common multiples of 30 and 42 and can be found by multiplying 210 by successive counting numbers.
210 x 1 = 210
210 x 2 = 420
210 x 3 = 630 and so on.

The Least Common Multiple (LCM) for 11 17 is 187. All you do is find the multiples of 11 and on the 17th one you'll get 187 and for 17 on the 11th multiple will be 187 and that their Least Common Multiple.
Oh, what a happy little question! To find the least common multiple of 12 and 22, we first need to find the multiples of each number. The multiples of 12 are 12, 24, 36, 48... and the multiples of 22 are 22, 44, 66, 88... The least common multiple is the smallest number that appears in both lists, which in this case is 132. Just a little math magic to brighten your day!
To find the LCM of 2+ multiples, you have to write the multiples of it out first.So, in this case, it's 12 and 9.12: 12,24,36,48,etc..9: 9,18,27,36, etc...so the LCM is 36.Recommend please! :D
You need two numbers to find a least common multiple. The LCM (least common multiple) is the smallest positive whole number exactly divisible by two or more given whole numbers. The C in LCM stands for common and in general we only talk about common multiples of two or more numbers.You need at least two numbers to find an LCM.
common multiples of 45 are 9 and 5 and common multiples of 8 are 4 and 8. This person doesn't know what common multiple is. (up) New author: You have to find if it is the LCM or the MCM, Least common multiple is 360 New author: MCM can't exist, it is no point finding it. Every MCM of multiple numbers are always infinity
