what multiples do 7,5 and 9 have that are the same
8 and 9 are corpime, so their first common multiple is their product. The next common multiples are simply the multiples of that first multiple.The first three common multiples are therefore 72, 144 and 216.
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.
My thinking is 36,72,108
The first six multiples of 3 are 3, 6, 9, 12, 15, and 18.
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.
Common multiples of 7 and 4 include any multiple of 28.
They are 63 and 126
63
9, 18, 27, 36, 45, 54, 63.
63, 126, 189.
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27

126, 252, 378
They are the first three multiples of LCM(5, 9), that is, the first three multiples of 45.
The LCM of 7 and 9 is 63.
