Web6 feb. 2024 · ax + by = gcd (a, b) Let us put b = prime, we get ax + prime * y = gcd (a, prime) We know gcd (a, prime) = 1 because one of the numbers is prime. So we know ax + prime * y = 1 Since prime * y is a multiple of prime, x is modular multiplicative inverse of a . ax ≡ 1 (mod prime) We can recursively find x using below expression (see extended ... Web6 sep. 2015 · 8 is the correct answer indeed. 7*4/11 mod 10 means we're looking at 7*4*x mod 10 where x is the modular inverse of 11 modulo 10, which means that 11*x mod 10 = 1 . This is true for x=1 ( 11*1 mod 10 = 1) So 7*4*x mod 10 becomes 7*4*1 mod 10 which is 28 mod 10 = 8. Share.

WebA modular square root r of an integer number a modulo an integer m greater than 1 is an integer such that: r 2 ≡ a ( mod m) In this article we will consider the case when the modulus is prime. Otherwise we can compute the square roots modulo the prime factors of m and then generate a solution using the Chinese Remainder Theorem.

"WebThe Euclidean Algorithm gives you a constructive way of finding r and s such that ar + ms = gcd (a, m), but if you manage to find r and s some other way, that will do it too. As soon as you have ar + ms = 1, that means that r is the modular inverse of a modulo m, since the equation immediately yields ar ≡ 1 (mod m). " - How to calculate modular
