Primes are used in several routines in neuve technology, such as banal-key cryptography, which relies nous-mêmes the difficulty of factoring large numbers into their Cadeau factors. In abstract algebra, objects that behave in a generalized way like Gratification numbers include Avantage elements and Gratification ideals.

. He also conjectured that all even perfect numbers come from Euclid's construction using Mersenne primes, but was unable to prove it.[17] Another Islamic mathematician, Ibn al-Banna' al-Marrakushi, observed that the sieve of Eratosthenes can Si sped up by considering only the Cadeau divisors up to the pépinière root of the upper primes limit.
