Prime Factorization - Factor Tree with 3 Factors - Explain (Level 2)

This math topic focuses on prime factorization using factor trees specifically with three factors and includes explaining these structures. It tests the ability to deduce and verify the correct pairs of factors that multiply together to form a product, represented by questions in which learners must select the correct pair of numbers that equal the product shown at the top of each factor tree. The problems are depicted through visualizations of the trees, with various pair combinations given as multiple-choice answers. This topic is designed to reinforce understanding of factor trees and the concept of prime factorization.
