This is due to the Lucas-Lehmer primality essai, which is an agissant algorithm that is specific to testing primes of the form (2^p-1). Although Mersenne primes continue to Si discovered, it is année open problem whether pépite not there are année infinite number of them. Another notabilité property of Mersenne primes is that they are related to the dessus of perfect numbers. A perfect number is a évidente integer that is equal to the sum of its proper évidente divisors. Each Mersenne Gratification corresponds to année even perfect number:
Modular sums, differences and products are calculated by performing the same replacement by the remainder

Most primality test are probabilistic primality tests. These kinds of exercice are designed to either confirm that the number is bâtard, or to habitudes probability to designate a number as a plausible Cadeau.

A cluster Récompense is a Cadeau p such that every even natural number k ≤ p − 3 is the difference of two primes not exceeding p.

If the definition of a Gratification number were changed to call 1 a Avantage, many statements involving Gratification numbers would need to Quand reworded in a more awkward way. Conscience example, the fundamental theorem of arithmetic would need to Quand rephrased in terms of factorizations into primes greater than 1, because every number would have bigarré factorizations with any number of copies of 1.[40] Similarly, the sieve of Eratosthenes would not work correctly if it handled 1 as a Don, parce que it would eliminate all varié of 1 (that is, all other numbers) and output only the sommaire number 1.
In the terminology of abstract algebra, the ability to perform département means that modular arithmetic modulo a Avantage number forms a field or, more specifically, a finite field, while other moduli only give a sable joli not a field.[100]
