Webb23 sep. 2024 · Three applications of Euler’s theorem. Posted on 23 September 2024 by John. Fermat’s little theorem says that if p is a prime and a is not a multiple of p, then. ap-1 = 1 (mod p ). Euler’s generalization of Fermat’s little theorem says that if a is relatively prime to m, then. aφ (m) = 1 (mod m) where φ ( m) is Euler’s so-called ...

Application of Fermat’s Little Theorem in Congruence
WebbA simple Math Problem. By Frankenstein123 , history , 4 years ago , Let's suppose I need to calculate a b c modulo 10 9 + 7, with the constraints 1 ≤ a, b, c ≤ 10 18. I can calculate a n s = b c in O ( l o g ( c)), with modulo 10 9 + 6, (probably everyone knows how) and then calculate a a n s with modulo 10 9 + 7. Webb29 jan. 2024 · Definition. A modular multiplicative inverse of an integer a is an integer x such that a ⋅ x is congruent to 1 modular some modulus m . To write it in a formal way: we want to find an integer x so that. a ⋅ x ≡ 1 mod m. We will also denote x simply with a − 1 . We should note that the modular inverse does not always exist. greatest hits ps4
