Final answer:
The number that is a factor of the prime factorization of 60 is 3.
Step-by-step explanation:
Factors are numbers that divide evenly into another number. To find the factors of 60, we need to find all the numbers that divide evenly into 60. The prime factorization of 60 is 2 x 2 x 3 x 5.
Therefore, the numbers that are factors of the prime factorization of 60 are 2, 3, and 5. So, the number that is a factor of the prime factorization of 60 is 3.
