Question

find the GCF of 14a5 and 22a3

Answer 1

I am assuming that you mean $14 a^{5}$ and $22 a^{3}$

Now, let's look for common factors.  The first one is $a^{3}$  After we take that out, we are left with 14 and 22.  We can take a 2 out of both of these, so the greatest common factors is $2a^{3}$
