4, 8, 12
4, 8 and 12 are the first 3 common multiples of 2 and 4
The first six multiples of 8 are 8, 16, 24, 32, 40, and 48. The first six multiples of 12 are 12, 24, 36, 48, 60, and 72. Multiples are obtained by multiplying the number by integers (1, 2, 3, etc.).
I think they are 24, 48 and 72.
The common multiples of 3 and 8 are 24, 48, 72, 96, 120, and so on. The LCM (least common multiple) of 3 and 8 is 24.
lcm(2, 7) = 14 → first 3 common multiples are: 14, 28, 42; lcm(2, 8) = 8 → first 3 common multiples are: 8, 16, 24; lcm(7, 8) = 56 → first 3 common multiples are: 56, 112, 168; lcm(2, 7, 8) = 56 → first 3 common multiples are: 56, 112, 168.
8, 16, 24
First 3 multiples of: 3: 3, 6, 9 8: 8, 16, 24 9: 9, 18, 27 72, 144, 216
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
24, 48, 72
They are the multiples of 3*8 = 24
The firt three multiples of 8 are 8, 16 and 24.

72
It is 120.
The first three multiples of 4 are 4, 8 and 12. For them to be common, they need to be compared to another set of multiples.
