Because the LCM of 12 and 56 is 168 and 336 is the next common multiple
28 and 56
12, 24, 36, 49, 60, 72, 84 28, 56, 84
No, 2 and 28 are not multiples of 56, they are factors.
The common multiples of 8 and 12 that are less than 100 are 24, 40, 48, 56, 64, 72, 80, 88, and 96.
The common multiples of 7, 8, and 8 are the infinite set that includes any multiple of 56. The common multiples are thus 56, 112, 168, 224, 280, and so on.
