Question 689821: The product of three whole numbers is 60 and their sum is 13. The numbers are all different and greater than 1. We need to find the three numbers with the detailed working of the solution. Answer by KMST(5328) (Show Source):
You can put this solution on YOUR website! Since the sum of the three numbers is 13, either all three numbers are odd, or only one of them is odd. (prime factorization of )
By associating (putting in brackets) two of those four factors, that product can be split into three greater than 1 factors several ways:
A
B
C
D
We eliminate option D because the three factors are not all different.
I eliminate option A because I need to count on my fingers to add, and since the three factors include only two odd numbers, their sum will be even, and cannot be 13. (You can add if you want).
I have to add for options B and C:
B is not the answer
C is the answer.
