This math topic focuses on prime factorization using factor trees, specifically requiring students to determine which pair of factors multiplies to produce the number at the top of the tree. Each problem shows a partially completed factor tree with two factors, highlighting one pair of these factors. Students must select the correct answer that identifies which of the given pairs of numbers when multiplied together would correctly form the number shown above them in the tree. This exercise is part of an introductory unit on factoring and primes.
