10, (lowest number that is divisible by 2 and 5).
The Least Common Multiple (LCM) for 2 3 5 is 30.

30
The lowest common multiple is 60.
The lowest common multiple of 5 and 9 is 45
Both 2 and 5 are prime numbers so their product 2 x 5 = 10 is the Lowest (or Least) Common Multiple. The common multiples of 2 and 5 are therefore any number which is a multiple of 10.
The LCM is: 25
What are 2 multiples that 3 and 5 have in common
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.
