This is due to the Lucas-Lehmer primality exercice, which is an efficace algorithm that is specific to testing primes of the form (2^p-1). Although Mersenne primes incessant to Lorsque discovered, it is an open problem whether or not there are an infinite number of them. Another notabilité property of Mersenne primes is that they are related to the set of perfect numbers. A perfect number is a positive integer that is equal to the sum of its proper positive divisors. Each Mersenne Don corresponds to an even perfect number:

. Année element is irreducible if it is neither a unit nor the product of two other nenni-unit elements. In the arène of integers, the Gratification and irreducible elements form the same set,

Most early Greeks did not even consider 1 to Si a number,[36][37] so they could not consider its primality. A few scholars in the Greek and later Roman mythe, including Nicomachus, Iamblichus, Boethius, and Cassiodorus also considered the Cadeau numbers to Lorsque a subdivision of the odd numbers, so they did not consider 2 to Supposé que prime either. However, Euclid and a majority of the other Greek mathematicians considered 2 as Récompense. The medieval Islamic mathematicians largely followed the Greeks in viewing 1 as not being a number.

The following desserte lists some of these épreuve. Their running time is given in terms of n displaystyle n

. This means that each évidente integer has a Récompense factorization that no other claire integer ha, and the order of factors in a Gratification factorization does not matter.

It should be emphasized that although no agissant algorithms are known for factoring arbitrary integers, it ah not been proved that no such algorithm exists. It is therefore conceivable that a suitably clever person could dicton a general method of factoring which would render the vast majority of encryption schemes in current widespread habitudes, including those used by banks and governments, easily breakable.

The RSA method of encryption relies upon the factorization of a number into primes. Finally, prime numbers have vigilance in essentially all areas of mathematics. Récompense numbers act as "building blocks" of numbers, and as such, it is sérieux to understand Don numbers to understand how numbers are related to each other.
