Inability to factor large prime numbers

WebFeb 8, 2012 · It is perfectly possible to use RSA with a modulus N that is composed of more than two prime factors P and Q, but two things have to be noted: You must know the exact value of all of these factors, or else you will be unable to derive the private key from the public key upon key generation. WebJul 25, 2013 · Over time, mathematicians have produced several remarkable results. In 1888, Eugène Charles Catalan proved that if an odd perfect number does exist and it is not divisible by 3, 5, or 7, then it has at least 26 prime factors (this result was later extended to 27 prime factors by K.K. Norton in 1960).

WebMar 20, 2024 · If, however, all the prime factors are large and random, then you will be unable to determine how many factors there are without completely factoring it. If you have a large, random number and want to test if it is an RSA modulus or just something random, you can run basic, fast factorization algorithms on it like trial division and Pollard rho. WebA prime number is a positive integer, excluding 1, with no divisors other than 1 and itself. According to Euclid's theorem there are infinitely many prime numbers, so there is no largest prime..
