To find the GCF between terms, it's necessary to analyze the number and variable part of each term. Notice that 4a
are both factors of this term. Additionally, 4
can be written in terms of its factors. This gives
The second term of the original expression, 2,
does not have any variable part. Thus, it can be written in terms of its factors as
Notice that 4a
both share a factor of 2.
is the GCF. Factoring 2
out of the expression gives
Following the same process as above, the terms in this expression can be written in terms of their factors.
Notice that each term contains a 2
and an x
in its factors. Thus, 2x
is the expression's GCF. Factoring 2x
