This gives you two options. One, use brute force to break

I think you may mean something slightly differently; given any large
prime p, I can factor it completely extremely quickly:

p = 1 * p

There are no other factors; this *is* the prime factorization. :) Bill
Gates made the same mistake in his book _The Road Ahead_. Factoring
large primes is trivial; the prime factorization of large numbers is
hard, and I guess that's what you meant.

 And if the problem of factoring large numbers into primes was indeed
solved (this is probably what you meant), I think you'd very quickly
see a complete replacement of crypto systems in use today by the
governments with such security services.

Oh no, the whole security of computing has just fallen over, since you've shown that primes don't exist. What next, 
proving that black is white and getting run over on a zebra crossing? 

The whole security of encryption rests on the belief that prime factorization isn't possible in a reasonable time, and 
it may well have been solved. Why would any government admit that it had cracked RSA security and its derivates? I 
realise that we are getting into the realms of conspiracy theories now, however history shows that the UK did not wish 
it to be made public during the war that it had cracked the Enigma code. Why should it be any different now?

A prime is defined as being divisible by itself and 1 only, so for the purpose of the definition, 1 is not a factor.

Even if Embryonic Stem Cell Research yielded medical treatments, how could enough eggs be obtained to make them viable? 
We can't even get enough organs for transplant donation.
