The common multiplesof 12 and 56 are the multiples of their lowest common multiples, which is 168, namely:
168, 336, 504, 672, 840, 1008, 1176, 1344, 1512, 1680, 1848, 2016, 2184, 2352, 2520, 2688, 2856, 3024, 3192, 3360, 3528, 3696, 3864, 4032, 4200, 4368, 4536, 4704, 4872, 5040, 5208, 5376, 5544, 5712, 5880, 6048, 6216, 6384, 6552, 6720, 6888, 7056, 7224, 7392, 7560, 7728, 7896, 8064, 8232, 8400, 8568, 8736, 8904, 9072, 9240, 9408, 9576, 9744, 9912, 10080, 10248, 10416, 10584, 10752, 10920, 11088, 11256, 11424, 11592, 11760, 11928, 12096, 12264, 12432, 12600, 12768, 12936, 13104, 13272, 13440, 13608, 13776, 13944, 14112, 14280, 14448, 14616, 14784, 14952, 15120, 15288, 15456, 15624, 15792, 15960, 16128, 16296, 16464, 16632, 16800, ...
Because the LCM of 12 and 56 is 168 and 336 is the next common multiple
12, 24, 36, 49, 60, 72, 84 28, 56, 84
168 and 336
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.
56
56
The multiples of 28 include 28, 56 and 84. For them to be common, they need to be compared to another set of multiples.
4, 8, 12 and so on. 7, 14, 21 and so on. Common multiples include 28, 56, 84 and so on.
1 All the common multiples of 56 and 60 are: 1,2,4
