It's the exact definition of square free

If n is square-free, then a=n and b=1

If n is a square, then a=1 and b=n

If n is not square free, nor a square, it means that there exists integers m>1 and k>1 such that

If k is square free, then you are done : b=mē and a=k

If k is not square free, then there exists integers p>1 and q>1 such that

So

If q is square free...

If q is not square free...

And so on...
