It is
2 - What is the highest degree of that divides evenly into
and
?
It is 1, since is not in every term.
3 - Multiplying the results above,
The GCF is 4.
2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3) Simplify each term in parentheses.
4) Factor out common terms in the first two terms, then in the last two terms.
5) Factor out the common term .
