Prime Factorization - Factor Tree with 4 Factors - Explain (Level 2)

This math topic focuses on prime factorization using a factor tree with four factors, where students are tasked with explaining specific parts of the tree. Each problem presents a factor tree and requires students to identify the meaning of a highlighted pair of numbers in terms of their multiplicative relationship. The emphasis is on understanding how multiplication of the pairs results in the numbers above them in the tree. This set of problems is designed to enhance students' understanding of factors, prime numbers, and the concept of building factor trees.
