Since 3 is a factor of 15, the first three common multiples of 3 and 15 are 15, 30, and 45.
To start with the 3 common multiples of 5 they are........10,15,and 25the 3 common multiples of 3 are.........15,30,and 45hope this helped=)

They are the six multiples of 15.
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.
Only one can be least; that's 15. Other common multiples include 30 and 45.
