Common multiples include 75, 150, 225 and so on.

There is an infinite number of common multiples for 3 and 15. A common multiple of any two or more numbers is any number into which each of two or more numbers can be divided evenly (zero remainder). However, the least or lowest common multiple (LCM) of 3 and 15 is 15.

20, 40, 60 and so on. 30, 60, 90 and so on. Common multiples include 60, 120, 180 and so on.

100, 200, 300

The least common multiple of 3 and 9 is 9. because: Multiples of three are: 3, 6, 9, 12, 15... Multiples of nine are: 9, 18, 27, 36.... The Least Common Multiple (LCM) there in both of the numbers is 9.
