4, 8, 12
4, 8 and 12 are the first 3 common multiples of 2 and 4
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.
5 + 10+15+20=50 ans
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
