    x^2+2y^2+z^2=xyz Diophantine Equation

    I think $$x,y,z$$ must be multiple of 4 but I couldn't go on.

    How can I effectively solve a system of congruences?

    My attempt. I think it might be that I solve the diophantine equation wrong, according to my anwer key it should be I do not get a particular solution that is close to 397 as you can see.
