    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.
