Finding the Greatest Common Factor

The video tutorial explains how to find the greatest common factor (GCF) of two numbers by listing factor pairs. It begins with a word problem involving treat bags and introduces the concept of factors and factor pairs. The tutorial outlines three steps to find the GCF: listing factor pairs, identifying common factors, and selecting the largest common factor. A practical example is provided, showing how to use the GCF to solve the treat bag problem, resulting in eight equal treat bags. The lesson concludes by reinforcing the application of GCF in solving word problems.
