I need to write up how to find a greatest common factor in a polynomial. I am having a hard time doing so. Could someone help me please?

Do you mean greatest common factor in two polynomials?
I would factor each one, circle the common factors, and multiply them together.
For example:
x^31 = (x1)(x^2+x+1)
x^21 = (x1)(x+1)
The only common factor is (x1), so the GCF is (x1).
