factor each number into prime numbers:

note:  the second 8 doesn't change anything.  for example, the lcm of 8 and 8 is 8, the lcm of 8 and 8 and 8 is 8, and so on.  repeating a number doesn't do anything

8 = 2 * 2 * 2

4 = 2 * 2

15 = 3 * 5

3 = 3

5 = 5

6 = 2 * 3

the lcm is 2 * 2 * 2 * 3 * 5 because 2 * 2 * 2 * 3 * 5 has 2 * 2 * 2 (to make 8), 2 * 2 (to make 4), 3 * 5 (to make 15), a 3 (to make 3), a 5 (to make 5), and 2 * 3 (to make 6).

2 * 2 * 2 * 3 * 5 = 120

the lcm of 8, 4, 15, 3, 5, 6, and 8 is 120
