Simplifying Fractions and Factors

The video tutorial explains how to multiply three fractions by multiplying their numerators and denominators. It emphasizes the importance of simplifying the product by removing common factors. Two methods for simplification are demonstrated: using prime factorization and identifying common factors directly. The tutorial highlights the advantages and challenges of each method, ensuring the final product is in its simplest form.

What is the first step in multiplying fractions?
