32 • ____ = 63What number completes the prime factorization of 63?

The prime factorization of 63 is 3 • 3 • 7.

To find the missing number in the equation 32 • ____ = 63, we need to divide 63 by 32.

63 ÷ 32 = 1.96875

Therefore, the number that completes the equation is 1.96875. However, this is not a prime number, so it does not complete the prime factorization of 63.

The question seems to be a bit confusing as the prime factorization of 63 does not involve the number 32.
