WebPrime numbers¶. Public key cryptography uses many fundamental concepts from number theory, such as prime numbers and greatest common divisors. A positive integer \(n > 1\) is said to be prime if its factors are exclusively 1 and itself. In Sage, we can obtain the first 20 prime numbers using the command primes_first_n: WebNumber Theory# Sage has extensive functionality for number theory. For example, we can do arithmetic in \(\ZZ/N\ZZ\) as follows: sage: R = IntegerModRing (97) sage: a = R (2) / R (3) sage: a 33 sage: a. rational_reconstruction 2/3 sage: b = R (47) sage: b ^ 20052005 50 …

WebIn fact, there was already a general question asked there about Sage versus other software, and the top answer said, "If you are doing graph theory or serious number theory, you shouldn't even be asking the question of which package to use." That is, if you're doing graph theory, or serious number theory, Sage is the winner by far.

In other words, the multiplicative order of a modulo n is the order of a in the multiplicative group of the units in the ring of the integers modulo n.. The order of a modulo n is sometimes written as ⁡ ().
