Why is it useful to factor out the GCF first when factoring?

From Google: It's useful to divide out the GCF first because it makes factoring easier because the coefficients are smaller requiring less steps. ... Factoring by grouping often works well with four-term polynomials but the last step of factoring the common binomial only works when both terms contain the exact same binomial.

Basically it just makes the coefficients smaller so it is easier to find common factors.

Hope this helps!
