PTIME - Prime Time


For your math homework this week your teacher gave you five large numbers and asked you to find their prime factors. However these numbers aren't nearly large enough for someone with knowledge of programming like yourself. So you decide to take the factorial of each of these numbers. Recall that N! (N factorial) is the product of the integers from 1 through N (inclusive). It’s your job now to create a program to help you do your homework.

Input

Each test case contains a number N (2 ≤ N ≤ 10000).

Output

The output should contain a line representing the prime factorization of the factorial given number, which should be of the form: p1^e1 * p2^e2 * ... * pk^ek where p1, p2, ... pk are the distinct prime factors of the factorial of the given number in increasing order, and e1, e2, ... ek are their exponents.

Example

Input:
10

Output:
2^8 * 3^4 * 5^2 * 7^1
