Prime Factorization - Factor Tree with 4 Factors - Explain (Level 1)

This math topic focuses on practicing prime factorization using factor trees, with a specific emphasis on understanding how multiplication pairs lead to the product represented above them in the tree. Each question presents a factor tree with pairs of factors that multiply together to form a number, and the task is to identify the correct pair that results in a highlighted number. This topic is part of a broader unit on factoring and primes for beginners, enhancing understanding of fundamental multiplication relationships within factor trees.
