Math Question

This was on a math team test today.

xyz = 4(x+y+z), Find all possible integer values of x, y, and z. there was more to the question, but it was fluff. Take a crack at it. We were given an explanation to the answer, but I didn’t have enough time to read it.

So, take a crack, see if you can get it :slight_smile: Explain it if you do.
