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. It’s your job now to create a program to help you do your homework.
The input file DATA2.txt will contain 5 test cases. Each test case contains a number N (2 ≤ N ≤ 10000).
The output file OUT2.txt will contain 5 lines of output, each representing the prime factorization of the 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 given number in increasing order, and e1, e2, ..., ek are their exponents.
