63, 126, 189 and so on.
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.
315
There are an infinite number of common multiples for 7 and nine. Some of them are 63, 126, 189, 252, 315, and 378.63
Any multiple of 252
They are 63 and 126
63
Common multiples of 9 and 10 are all of the multiples of 90.
63, 126, 189.
Multiples of 3 are 3, 6, 9 and so on. Multiples of 7 are 7, 14, 21 and so on. The common multiples of 3 and 7 include 21, 42, 63 and so on.
