Prime Factorization - Factor Tree with 2 Factors - Finish (Level 2)

This math topic focuses on practicing prime factorization using factor trees, specifically requiring only a pair of factors for completion. Students work through several problems where they must analyze partial factor trees and select the correct sequence of prime factors that multiply to form the given number. The sheet covers a range of numbers to factorize, employing basic and more complex primes to foster a deeper understanding of factorization in the context of prime numbers. The exercises build foundational skills in recognizing and using prime numbers in arithmetic operations.
