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

This math topic focuses on practicing prime factorization using factor trees, specifically with scenarios involving three factors. The problems engage students in constructing and interpreting factor trees to understand how pairs of numbers multiply to produce the numbers above them. Each question presents a visual factor tree and multiple-choice answers to confirm the product of highlighted number pairs. This helps develop skills in prime factorization, multiplication, and critical thinking regarding number relationships.
