the product of six whole numbers is 36. What is the least possible value of their sum?

Answer 1

I assume that some of the numbers can be the same, otherwise the least possible multiplication would be
1x2x3x4x5x6 = 720

so to get 36 using the smallest possible numbers would be
1x1x2x2x3x3
and the least possible sum = 15

Answer 2

fake answer. wasting of time.. use less
