Prime Factorizatio

Is Number a Factor - From Value as Factors (Level 1)

This math topic practices skills involving prime factorization and determining if one number is a factor of another using those factorizations. Problems include analyzing the prime factors of two different numbers and answering whether the first number is a factor of the second. For instance, given two numbers expressed as products of their prime factors, learners must decide if the first number divides the second without a remainder. This is an introductory level practice within a broader study on factoring and the greatest common factor.
