Sum and product of factors of a semiprime

Hi all, I'm new on this forum (it is great (Happy) )

I have a maybe-hard maybe-easy question, which is the following (I have worked quite a lot on it but can't find a way around it) :

Say , with p and q [non-trivial] primes (so n is semiprime)

Now say (same values of p and q obviously)

I know "n", but I need "m" (I don't know p or q). Is there a way around this, or is it just impossible ? Isn't there some kind of relation between the product and the sum of the factors of any semiprime ?

Regards.
