There is no greatest common multiple: for whatever value you say is the greatest I can always add their lowest common multiple and get an even greater common multiple.
There is a greatest common FACTOR or a LOWEST common multiple:
gcf(27, 6) = 3
lcm(27, 6) = 54
Using the factorisation method:
27 = 3³
6 = 2 x 3
hcf = 3
lcm = 2 x 3³ = 54

There is no greatest common multiple. Ever! If x were the greatest common multiple, then what about 2x? Since x is a multiple of 16 and 24 then so also is 2x, so that 2x is a COMMON multiple. And it would certainly be greater that x. So 2x is a common multiple that is greater than the greatest common multiple. What?!
