Factors, Multiples, and Prime Factorization

The video tutorial introduces the concepts of factors and multiples, explaining how to find them using various methods such as charts and prime factorization. It covers the greatest common factor (GCF) and least common multiple (LCM), providing examples and strategies for determining these values. The tutorial also demonstrates how to list factors and multiples, offering practical examples to reinforce understanding.
