WebA modular multiplicative inverse of a modulo m can be found by using the extended Euclidean algorithm. The Euclidean algorithm determines the greatest common divisor (gcd) of two integers, say a and m. If a has a multiplicative inverse modulo m, this gcd must be 1. The last of several equations produced by the algorithm may be solved for this gcd.

"Web1 day ago · The modular inverse of a mod m exists only if a and m are relatively prime i.e. gcd (a, m) = 1. Hence, for finding the inverse of an under modulo m, if (a x b) mod m = 1 then b is the modular inverse of a. Example: a = 5, m = 7 (5 x 3) % 7 = 1 hence, 3 is modulo inverse of 5 under 7.

WebFrom the quotient remainder theorem we can write A and B as: A = C * Q1 + R1 where 0 ≤ R1 < C and Q1 is some integer. A mod C = R1 B = C * Q2 + R2 where 0 ≤ R2 < C and Q2 is some integer. B mod C = R2 (A + B) = C * (Q1 + Q2) + R1+R2 LHS = (A + B) mod C LHS = (C * (Q1 + Q2) + R1+ R2) mod C We can eliminate the multiples of C when we take the … WebLet x be the multiplicative inverse. Then 8x = 1 (mod 12). Multiplying both sides by 3, I get 24x= 3 (mod 12), or 0 = 3 (mod 12). This is a contradiction, since 0 and 3 do not diﬀer by a multiple of 12. Therefore, 8 does not have a multiplicative inverse mod 12. Proposition. m∈ Z

WebFermat's little theorem: If p is prime and does not divide a, then a p – 1 ≡ 1 (mod p). Euler's theorem: If a and n are coprime, then a φ(n) ≡ 1 (mod n), where φ is Euler's totient function; A simple consequence of Fermat's little theorem is that if p is prime, then a −1 ≡ a p − 2 (mod p) is the multiplicative inverse of 0 < a < p.
