If you want to find the LCM of two numbers, you first need to break those numbers down into their prime factors:

27=3x3x3

18=3x3x2

The next step is to discard the duplicate entries of any common prime factors. In this case, both numbers have two 3s in their prime factors, so we can discard 2 of these, leaving us with 3,3,3 and 2.

Multiply all these together for the LCM:

3x3x3x2 = 54

So the lowest common multiple of 27 and 18 is 54.
