Thanks Geno,
I think your answer is cool too :)
Attn: ibhar,
Thank you for responsing to Gino's answer so nicely.
BUT
You need to think.
Your statement: "I also assume that some non-odd primes work"
1) Firstly, tell me some non-odd primes.
2) second show me with one of them what the average of its factors is.
3) discuss your answers.
YES you are expected to answer me :)
