At class we found this programming problem, and currently, we have no idea how to solve it.

The positive integer n is given. It is known that n = p * q, where p and q are primes, p<=q and |q-k*p|<10^5 for some given positive integer k. You must find p and q.

Input:

35 1
121 1
1000730021 9

Output:

5 * 7
11 * 11
10007 * 100003

It's not a homework, we are just trying to solve some interesting problems. If you have some ideas, please post them here so we can try something, thanks.
