15 & 20 have an infinite number of Common Multiples; the first three are 60, 120 and 180.

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...

The way to solve this is as follows:Find the least common multiple of the two numbers.Multiply this least common multiple by 2 and by 3, to get the next two common multiples.

They are the six multiples of 15.

There are more than 5 multiples of three, but here are the first 5: * 6 * 9 * 12 * 15 * 18

45, 90, 135

Multiply 35 by the first three counting numbers. That will give you the first three multiples. To be common, they need to be compared to another set of multiples. If you meant 3 and 5, the LCM is 15. Multiplying 15 by 2 and 3 will give you the others.

60, 120 and 180

105, 210, 315
