The first two common multiples of 4 and 9 are 36 and 72. To find the common multiples, you need to list the multiples of each number and find where they intersect. The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, and so on. The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, and so on.
LCM(21, 49, 56) = 1176
28 and 56
28, 56, 84, and so on.
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.

52 and 56 are multiples of 4 and have 1, 2 and 4 in common. 54 and 57 are multiples of 3 and have 1 and 3 in common.
The multiples of 28 include 28, 56 and 84. For them to be common, they need to be compared to another set of multiples.
There are an infinite number of them. They include 28, 56, 476, and 532 .
The first two common multiples of 4 and 9 are 36 and 72. To find the common multiples, you need to list the multiples of each number and find where they intersect. The multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, 56, 60, 64, 68, 72, and so on. The multiples of 9 are 9, 18, 27, 36, 45, 54, 63, 72, and so on.
