The number 75 can be written as the sum of the squares of 3 different positive numbers. What is the sum of these 3 integers?

13, 14, 15, 16, or 17

Is there an easy way to solve this?

x+y+z = ?

x^2 + y^2 + z^2 = 75

1 = 1
2 = 4
3 = 9
4 = 16
5 = 25
6 = 36
7 = 49
8 = 64


49+25+1 = 75
7+5+1 = 13


I don't know any better way to handle it
