w is.
If they have no prime factors in common, the LCM of w and y is their product.

W is.
The factors of 5w are 5 and w.
You need at least two things to find something in common between them.
I regret that there is no such thing as "the greatest common w".
The greatest common factor is the largest of the common factors.
Ah, math time, my favorite! To reduce the fraction w^2 + 5w + 6 over w^2 - w - 12, first factor both the numerator and the denominator. The numerator factors into (w + 2)(w + 3), and the denominator factors into (w + 3)(w - 4). Cancel out the common factor of (w + 3) in both the numerator and the denominator, leaving you with (w + 2) over (w - 4). Voilà!
