Finding the Greatest Common Factor

The video tutorial explains how to find the greatest common factor (GCF) of two monomials. It begins by defining the GCF and then demonstrates the process of finding the prime factorization of the coefficients 108 and 96. The tutorial continues by identifying the common variable factors in the monomials and concludes by combining these factors to determine the GCF, which is 12x^5y^2.

What is the greatest common factor of two monomials?
