14 and 21
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.
The only Least Common Multiple (LCM) for 7 9 14 is 126.
There are infinitely many multiples of 9 and 21 so it is impossible to list them. One of their multiples is 9*21 = 189.
7, 14, 21, 28, 35, 42, 49, 56,63 that's it ...I think
14 and 21
126
126, 252, 378
3, 6, 9, 12, 15, 18, 21
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.
126, 252, 378 and so on.
If that's 9, 14 and 21, the first three common multiples are 126, 252 and 378.
The multiples of 7 are 7, 14, 21, 28, 35, 42, etc.The multiples of 14 are 14, 28, 42, etc.The multiples of 21 are 21, 42, etc.The least common multiple (LCM) of 7, 14, and 21 is 42
The common multiples of 9 and 21 are 63, 126, 189 and so on.
The four multiples of seven are 7, 14, 21, and 28.
The only Least Common Multiple (LCM) for 7 9 14 is 126.
