Any multiple of 252
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.
The lowest common multiple of 7 and 9 is 63. The common multiples of 7 and 9 are therefore the infinite set of multiples of 63. Thus, the common multiples of 7 and 9 are 63, 126, 189, 252, 315, 378, 441, 504, 567, 630, 693, and so on.
504 is the least common multiple of 7, 8 and 9. All numbers that are multiples of 504 are multiples of 7, 8 and 9 as well
Common multiples of 7 and 4 include any multiple of 28.
The LCM of 4, 9, and 12 is 36
The LCM of 9 and 12 is 36
The common multiples of 9 and 12 are 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, and so on. They are the infinite set of multiples of the LCM of 9 and 12, which is 36.
