The multiples of 3 up to 30 are: 3,6,9,12,15,18,21,24,27,30.The multiples of 5 up to 30 are: 5,10,15,20,25,30.The only common multiples are 15 and 30.The LCM is: 30
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
To find common multiples of two or more numbers, you can list the multiples of each.4, 8, 12, 16, 20, 24, 28, 32, 26, 40, 445, 10, 15, 20, 25, 30, 35, 40, 4520 and 40 are the common multiples that are listed. 20 is the Least Common Multiple (LCM).
15 and 30
Multiples of 3 less than 20 are {3,6,9,12,15,18}.
The multiples of 20 are 20, 40, 60, 80, 100, 120... The multiples of 30 are 30, 60, 90, 120, 150... The multiples of 15 are 15, 30, 45, 60, 75, 90, 105, 120, 135... The common multiples of 20, 30, and 15 are 60, 120, 180, 240...
Common multiples include any multiple of 60.
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 LCM of 20 and 30 is 60. The multiples of 20 are 20, 40, 60, and so on. The multiples of 30 are 30, 60, and so on. So teh LCM of 20 and 30 is 60.
20, 40, 60 and so on. 30, 60, 90 and so on. Common multiples include 60, 120, 180 and so on.
10, 20 and 30
The common multiples of 4 and 5 are 20, 40, 60, 80,100 and so onGet the least common multiple of the two. All other common multiples are multiples of this least common multiple.Any multiple of 20.
