20 is the smallest common multiple of 4, 5, and 10, and thus the first. Thus, the first three common multiples of 4, 5, and 10 are 20, 40 and 60.
20 pinkgal333:20, 40, 60 are all common multiples.

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.
10, 20, 30 The common multiples of 5 and 10 are multiples of their lowest common multiple. The lcm of 5 and 10, is 10. Thus the first three common multiples are 10, 20, 30.
The Lowest Common Multiple (LCM) of 3 and 10 would be 30
20, 40, 60 are all common multiples.
