Three numbers.
20 pinkgal333:20, 40, 60 are all common multiples.
20
20, 40, 60, 80 and so on.
5, 10, 15, 20
10 and 15 15 and 20 20 and 25
60, 120 and 180
The common multiples of 9, 15, and 20 are an infinite set of multiples of their least common multiple, which is 180. so the common multiples of 9, 15, and 20 are 180, 360, 540, 720, 900, 1080, 1260, 1440, 1620, 1800, and so on.
60 and all its multiples

LCD= 60
Ans: 15, 30 and 45 Prime factorization of 3 and 15 3: 3 15: 3 x 5 15, 30 and 45. Hi My names Bob
The LCM is 60
60 and 8,220
What are the first three common multiples of four and five
10, 20, 30 The common multiples of 5 and 10 are multiples of their lowest common multiple. The lcm of 5 and 10, is 10. Thus the first three common multiples are 10, 20, 30.
The Least Common Multiple (LCM) for 10 15 20 is 60.
