The least common multiple(LCM) is 12

Use some method which you probably already learned, to find the least common multiple. All the other common multiples are multiples of this least common multiple, so you can multiply the least common multiple by 2, by 3, by 4, etc., to get additional common multiples.

It is 12 and its multiples.

lcm(4, 9) = 36 → the two least common multiples (ie the first two common multiples) of 4 and 9 are 36 and 72.

The common multiples of 4 and 5 are 20, 40, 60, 80,100 and so onGet the least common multiple of the two. All other common multiples are multiples of this least common multiple.Any multiple of 20.

There are plenty of common multiples, but only one can be the least; thus the least common multiple of 4, 6, 9 is 36.

Since 4 is a multiple of 2, all the multiples of 4 will be common.
