Greatest Common Factor Concepts

This video tutorial explains how to determine the greatest common factor (GCF) of two or three integers, also known as the greatest common divisor (GCD). It demonstrates using the TI-84 calculator to find the GCF of two numbers and provides examples of factoring expressions by identifying the GCF. The video covers factoring the expression 60x - 72 and a polynomial with multiple terms, highlighting the process of using the GCF to simplify expressions.
