18, 36 and 54.
The factorization for 6 and 9 is:
6 = 2 x 3
9 = 3 x 3
The lowest number with all factors from 6 and 9 is 2 x 3 x 3 = 18.
To find the next common multiples, just keep adding 18 to the previous one.

The LCM is 30.
The answer that I got was 24, and any multiples of 24.
What are three common multiples of 2 6 8
The first three multiples of 3 are 3, 6, 9 The first three multiples of 9 are 9, 18, 27 As the lowest common multiples of 3 and 9 is 9, the common multiples of 3 and 9 are the multiples of 9, thus: The first three common multiples of 3 and 9 are 9, 18, 27
The LCM is: 12
