radical of an integer

Given a natural number $n$ , let $n=p_{1}^{{\\alpha}_{1}}\\cdots p_{k}^{{\\alpha}_{k}}$ be its unique factorization as a product of distinct prime powers. Define the of $n$ , denoted $\\mbox{rad}(n)$ , to be the product $p_{1}\\cdots p_{k}$ . The radical of a square-free number is itself.
