Find the largest number and highest degree of #a# that will divide evenly into all three terms in the equation. Multiply them to get the GCF.

Explanation:

#3a^3-6a^2-9a#

The greatest number that can be divided evenly into #3a^3,# #-6a^2,# and #-9a# is #3#.

The highest degree of #a# that can be divided evenly into #3a^3,# #-6a^2,# a #-9a# is #a#.

The GCF for the equation is #3*a=3a#.
