Largest n had been factored

  1. Mar 7, 2004 #1
    hi! i am looking for the largest integer "n" had been factored into 2 primes.
    eg. n=p*q where p,q are primes.

    any idea?

    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:
    is the product of two primes and has about 10 million digits.

    A site devoted to the largest known primes. The two Nate mentioned are the #39 (?) and #40 (?) Mersenne primes.

    this is where this should have gone :-p

    no problem......

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