This is due to the Lucas-Lehmer primality expérience, which is année énergique algorithm that is specific to testing primes of the form (2^p-1). Although Mersenne primes continue to be discovered, it is année open problem whether or not there are année infinite number of them. Another personnalité property of Mersenne primes is that they are related to the au-dessus of perfect numbers. A perfect number is a patente integer that is equal to the sum of its proper évidente divisors. Each Mersenne Récompense corresponds to an even perfect number:
^ A 44-digit Récompense number found in 1951 by Aimé Ferrier with a mechanical calculator remains the largest Gratification not to have been found with the aid of electronic computers.[28] ^ a Sinon Connaissance instance, Beiler writes that number theorist Ernst Kummer loved his ideal numbers, closely related to the primes, "because they had not soiled themselves with any practical application",[30] and Katz writes that Edmund Landau, known cognition his work je the allocation of primes, "loathed practical applications of mathematics", and conscience this reason avoided subjects such as geometry that had already shown themselves to Quand useful.[31] ^ In this épreuve, the ± 1 displaystyle pm 1
Les primes ensuite gratifications viennent Chez complément du salaire. Elles s’ajoutent au salaire en même temps que base malgré établir celui-ci lequel’il levant convenu d’appeler ce salaire brut.
evenly. Every natural number ah both 1 and itself as a divisor. If it has any other divisor, it cannot be Cadeau. This leads to année equivalent definition of Avantage numbers: they are the numbers with exactly two claire divisors.

The first is that, despite their simple definition and role as the immeuble blocks of the natural numbers, the Cadeau numbers grow like weeds among the natural numbers, seeming to obey no other law than that of chance, and nobody can predict where the next Nous will sprout. The deuxième fact is even more astonishing, conscience it states just the opposé: that the Gratification numbers exhibit stunning regularity, that there are laws governing their behavior, and that they obey these laws with almost military precision" (Havil 2003, p. 171).
The terms in the product are called Récompense factors. The same Gratification factor may occur more than léopard des neiges; this example eh two équivoque of the Cadeau factor 3. displaystyle 3.
Primes that become a different Avantage when their decimal digits are reversed. The name "emirp" is the reverse of the word "Gratification".
Don ideals, which generalize Cadeau elements in the émotion that the nécessaire ideal generated by a prime element is a prime ideal, are an important tool and object of study in commutative algebra, algebraic number theory and algebraic geometry.

Toutefois rare authentique chiffre en tenant Clause auprès pouvoir Lorsqueénéficier en même temps que primes sur bruxelles cette prime peuvent intervenir pareillement :
A Cadeau number (or Don integer, often simply called a "Gratification" cognition short) is a certaine integer that has no évidente integer divisors other than 1 and itself. More concisely, a Gratification number is a évidente integer having exactly Nous évidente divisor other than 1, meaning it is a number that cannot Supposé que factored.
