Venn Diagrams

This video tutorial explains how to use a Venn diagram to find the greatest common factor (GCF) and least common multiple (LCM) of two numbers, 60 and 72. It begins with the prime factorization of each number, then uses a Venn diagram to identify common factors and unique factors. The GCF is determined by the intersection of the circles, while the LCM is calculated by multiplying all factors. Finally, the video demonstrates how to simplify the fraction 60/72 using the GCF.

What is the primary purpose of a Venn diagram in mathematics?

• To solve algebraic equations
