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 LCM is: 168
8
All common multiples of 7, 10 and 8 are divisible by them. The lowest common multiple of them is 280, so all multiples of 280 are divisible by them, namely 280, 560, 840, 1120, ...
24
The LCM is 8
The answer that I got was 24, and any multiples of 24.
The LCM is: 88
The Least Common Multiple (LCM) for 8 10 15 is 120.
The lowest common multiple is 24
24
The common multiples of 6, 7, and 8 are the multiples of its least common multiple, which is 168.The LCM of 6, 7, and 8 is 168.168, 336, 504 and so on.
