You need at least two numbers for an LCM. If that's 3 and 6, the LCM is 6.
The LCM of all these numbers is 72. (LCM of 9, 6, 3 is 18.) (LCM of 18, 8, is 72.)

A LCM, or Lowest Common Multiple, of 6 is when 6 is the lowest number that is a common multiple of two of more numbers. As 6 has the four factors 1, 2, 3 and 6, the numbers for which 6 can be a LCM must comes from these (if 1 is one of the numbers, then the other numbers must either include 6 or both 2 and 3).
The LCM of these four numbers is 18.
They are: 3, 6 and 8
