Find two positive numbers satisfying the given requirements. the product is 156 and the sum is a minimum.

156 = 2*2*3*13

Product: Sum:

1) 156 = 2*78 2+78 = 80

2) 156 = 4*39 4+39=43

3) 156=12*13 12 + 13 = 26

4) 156 = 6*26 6+26 = 32

The numbers are 12 and 13, because their product is 156, and their sum is minimum of possible.
