This math topic focuses on practicing prime factorization using factor trees with three factors, where some factors are missing and need to be identified. Each question requires deducing the missing numbers such that the product of two numbers equals the number directly above them in the factor tree. The worksheet targets understanding and applying prime factorization skills in a structured factor tree format.
