If two positive integers a and b are written as a=(x^3) * (y^2) and b=x * ( y^3), x and y are prime numbers , then HCF (a,b) is ?

Expert Answer:

Hint
Compare the indices of 'x' and 'y'
As we are required to find HCF, find the lowest index of 'x' and 'y' respectively.
 
Lowest index of 'x' is 1
Lowest index of 'y' is y2
So HCF is xy2
