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

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".
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!
The greatest common factor is the largest of the common factors.
