Greatest Common Factor and Prime Factorization

The video tutorial reviews the concept of the greatest common factor (GCF). It explains the meaning of 'greatest', 'common', and 'factor', and demonstrates how to find the GCF of two monomials, 10cd² and 25c³d², by breaking down the numbers and identifying common factors. The tutorial concludes with the GCF being 5cd².
