WebThe ability (or inability) to generate or check for primes in a certain amount of time is fundamentally important to cryptographic systems such as RSA. However, the "practical" applications of prime numbers (to fields like physics, chemistry, etc.) are, as far as I understand, very few -- cryptography is the major application. 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.
