Four different positive integers have a product of 110.

What is the sum of the four integers?

Answer: 19

Explanation:

Let's break 110 down into its prime factors

110 = 11*10

110 = 11*2*5

110 = 2*5*11

We have three different prime factors that multiply to 110. However, the instructions say there are 4 integers that multiply to 110. To fix this, we can say

110 = 1*2*5*11

now we see that 1,2,5 and 11 multiply out to 110

They add to 1+2+5+11 = 3+16 = 19
