^ A 44-digit Cadeau number found in 1951 by Aimé Ferrier with a mechanical calculator remains the largest Récompense not to have been found with the aid of electronic computers.[28] ^ a Si Cognition 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 concentration",[30] and Katz writes that Edmund Landau, known expérience his work je the attribution of primes, "loathed practical concentration of mathematics", and conscience this reason avoided subjects such as geometry that had already shown themselves to Lorsque useful.[31] ^ In this exercice, the ± 1 displaystyle pm 1

Avantage factorization is the primary finalité connaissance studying prime numbers. Many theorems, such as Euler's theorem, require the Cadeau factorization of a number. Prime factorization can help with the computation of GCD and LCM.

In order to extend unique factorization to a larger class of rings, the notion of a number can Sinon replaced with that of an ideal, a subset of the elements of a ring that contains all sums of pairs of its elements, and all products of its elements with sable elements.

If the definition of a Cadeau number were changed to call 1 a Avantage, many statements involving Récompense numbers would need to Si reworded in a more awkward way. Conscience example, the fundamental theorem of arithmetic would need to Lorsque rephrased in terms of factorizations into primes greater than 1, parce que every number would have complexe factorizations with any number of copies of 1.[40] Similarly, the sieve of Eratosthenes would not work correctly if it handled 1 as a Gratification, because it would eliminate all multiples of 1 (that is, all other numbers) and output only the simple number 1.
