This math topic focuses on prime factorization and understanding multiples from expressions involving variables represented as factors. It is part of a broader unit on factoring and finding the least common multiple. The problems presented involve analyzing algebraic expressions to determine if one is a multiple of another. Each question provides expressions with prime factors for two numbers and asks whether one number is a multiple of the other, with options to answer 'Yes' or 'No'. This helps in reinforcing the understanding of factorization and its practical application in evaluating multiples.
