서로소인 자연수 $x,y,z$ 에 대해

$\left \lfloor \frac{y}{x} \right \rfloor+\left \lfloor \frac{z}{y} \right \rfloor+\left \lfloor \frac{x}{z} \right \rfloor=\left \lfloor \frac{x}{y} \right \rfloor+\left \lfloor \frac{y}{z} \right \rfloor+\left \lfloor \frac{z}{x} \right \rfloor$

를 만족하는 $x,y,z$ 가 무한함을 보이시오.
