Um, do you mean factored, or do you mean largest known n such that n=pq?

Not sure about the former. The latter probably grows by a couple of digits every week

yes, i mean the largest known n such that n=pq where p,q=primes

thx again

So really, what you're asking for is the two largest known primes. I'm not sure if this is the best option, but it's certainly big:
[tex](2^{20996011}-1)(2^{13466917}-1)[/tex]
is the product of two primes and has about 10 million digits.

this is where this should have gone :-p

no problem......

M^2 is the answer, where M is the largest known Prime.
