Suppose that x, y, z are positive integers satisfying \(x \le y \le z \), and such that the product of all three numbers is twice their sum. What is the sum of all possible values of z?

I don't understand your LaTex, but here are a couple of numbers that satisfy your question;

 

x = 1,  y= 3,  z = 8  and

 

x = 1,  y = 4,  z =5

Thanks. The latex is x is less than or equal to y which is less than or equal to z
