If two positive ingeters $a$ and $b$ are expressible in the form $a=p q^2$ and $b=p^3 q ; p, q$ being prime numbers, then $\operatorname{LCM}(a, b)$ is
If two positive integers $a$ and $b$ are written as $a=x^3 y^2$ and $b=x y^3$, where $x, y$ are prime numbers, then the result obtained by dividing the product of the positive integers $a, b$ by the $\operatorname{LCM}(a, b)$ is
