The first step, no matter what you are factoring, is always to factor out the '''Greatest Common Factor''', commonly referred to as the '''GCF'''.<br />

For example:

:<math>2a^2b^3+4a^4b^4c^3-2a^3b^3=2a^2b^3(1+2a^2bc^3-a)\,\!</math>

or

where

: <math>mn 3x^3-6x+9x^4= a,\ pq = c3x(x^2-2+3x^3)\,\!</math>

and
