3. HCF and LCM of algebraic expressions

Ramya chose two positive integers, $x$ and $y$ expressed in terms of primes as $x$ $=$ $r^{2}s$ and $y$ $=$ $r{s}^3$. She wants to find the greatest common divisor and the least common multiple of two integers, $x$ and $y$. Can you help her find them?

 

Greatest common divisor $=$ $i^i{i}^i$

 

Least common multiple $=$ $i^i{i}^i$
