The first three multiples of 10 are 10, 20 and 30. Since numbers don't stop, there are no last three.
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.

All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
10, 20, 30
The anser to that Q is 30.
