WebApr 14, 2015 · 1 Answer. This is an old question, but for anyone coming from Google or elsewhere who has this same question: SymPy has something akin to Sage's radical function (which finds the squarefree part of a number n), you can use sympy.ntheory.factor_.core (n, t=2). Therefore, core (n, 2) gives you the same as radical … WebJul 1, 2016 · sage; number-theory; Share. Improve this question. Follow asked Jul 1, 2016 at 4:54.

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 ().
WebPublic 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. #Some basic operations on big numbers ... else: ans = mygcd(n, m % n) return ans """ The extended gcd is also part of SAGE's library. xgcd(a,b) returns 3 numbers: …
