There are 3 such numbers: 30, 60, 90.
The first five common multiples are the first five multiples of the lowest common multiple. lcm(5, 6): 5 = 5 6 = 2 x 3 → lcm = 2 x 3 x 5 = 30 → first 5 common multiples of 5 and 6 are: 30 x 1 = 30 30 x 2 = 60 30 x 3 = 90 30 x 4 = 120 30 x 5 = 150
15, 30, 45, 60, 75
well five times two is ten so double five and you have the same multiples
Since the lowest common multiple of 3 and 5 is 15, the common multiples of 3 and 5 are the multiples of 15: 30, 45, 60, 75, 90, etc...
Numbers which are the factors of thirty and multiples of five are 5, 10, 15 and 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.
The first five nonzero multiples of 6 are 6, 12, 18, 24 and 30.
30, 60, 90, 120, 150
First three common multiples of 5 and 6 are 30, 60 and 90.
Any multiple of 30.
30
30, 60, 90, 120, 150, 180.
The two common multiples of three and five are: 15 and 30 ^-^
The LCM is: 30
6, 12, 18, 24, 30.
There are 3 such numbers: 30, 60, 90.
