Largest Prime Factor

Given a positive integer \(n\) (with \(n > 1\)), your task is to find the largest prime factor of \(n\). A prime factor of \(n\) is a prime number that divides \(n\) without leaving a remainder. In mathematical terms, if \(p\) is a prime factor of \(n\), then \(p \mid n\). The answer for a prime number is the number itself.

Input: A single integer \(n\) from standard input.

Output: Output the largest prime factor of \(n\) to standard output.
