Step-by-step explanation:
The greatest common factor of

and

is
gcd(m*m*n*n, m*n*n*n) =m*n*n=

what we did, was to see how many m's and how many n's, each expression have, and then pick the smallest of each letter (factor).
the reason is that the common factor, must have enough m's and n's to divide the m's and n's of both expressions
so

also

thus, n is equal to 3
