then, in that case, you are dealing with a special case.

Anyways, the problem should then be, factor a prime * a prime, not factor any number?

prime factoring is easy. Just not prime * prime?

For example, guessing 2 nails it 50% of the time. How does that help you factor any specific number, especially one which is the product of two large primes? Answer: it doesn't.
