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.


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


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.



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

Yes, each input file only contains one number. Jared's comment implied otherwise, and I hadn't bothered submitting before because to me it's not a very interesting problem. The problem statement is still unclear, but anyway it's not necessary to read until EOF.

FOR EVERYONE WHO IS GETTING A WA...the value of N>(10^4) for some test cases...i was also a victim and it did cost me 6 WA's.. :@

Hi! Please check my solution. I just can't figure out why it gives a wrong answer!

sir please check my submission id..#7896221

my result exactly matches to that on!

is there some problem in the output format..?
