4. HCF and LCM of algebraic expressions

Ramya chose two positive integers, \(x\) and \(y\) expressed in terms of primes as \(x\) \(=\) $a^6{b}^2$ and \(y\) \(=\) $a^4{b}^4$. 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 \(=\) $i^i{i}^i$
