Question

# If the product of five integers is a multiple of 32, then what is the smallest number of these integers that must be even? a. 10 b.12 c. 14 d.15 e. 16

Probability and combinatorics
This problem makes no sense. There are 5 integers, only one needs to be even if it's a multiple of 32. $$32 \cdot 3 \cdot 5 \cdot 7 \cdot 9$$ is a multiple of 32. None of your answers make any sense.
