Find the GCF and LCM using prime factorization

This video tutorial explains how to find the greatest common factor (GCF) and least common multiple (LCM) of two whole numbers using their prime factors. It covers the concepts of prime and composite numbers, demonstrates the use of factor trees for prime factorization, and clarifies common misunderstandings between factors and multiples. The tutorial provides step-by-step examples of finding the GCF and LCM for the numbers 8 and 30, as well as 18 and 27, using Venn diagrams to compare prime factors.
