Quizplus · Accepted Answer

63 is not a prime number, and can be broken down into 3, 3, and 7, making the prime factorization 3 ∙ 3 ∙ 7. Therefore, the best choice is letter D. Choices A and C are incorrect, as 9 and 3 are not prime numbers and cannot be used in a prime factorization. Choice B is incorrect, as 7 cannot go into 63 evenly more than once.
