Chinese remainder theorem worked example
WebThe Chinese Remainder Theorem Kyle Miller Feb 13, 2024 The Chinese Remainder Theorem says that systems of congruences always have a solution (assuming pairwise coprime moduli): Theorem 1. Let n;m2N with gcd(n;m) = 1. For any a;b2Z, there is a solution xto the system x a (mod n) x b (mod m) In fact, the solution is unique modulo nm. WebThe Chinese Remainder Theorem Chinese Remainder Theorem: If m 1, m 2, .., m k are pairwise relatively prime positive integers, and if a 1, a 2, .., a k are any integers, then the …

WebExample Find the smallest multiple of 10 which has remainder 2 when divided by 3, and remainder 3 when divided by 7. We are looking for a number which satisfies the congruences, x ≡ 2 mod 3, x ≡ 3 mod 7, x ≡ 0 mod 2 and x ≡ 0 mod 5. Since, 2, 3, 5 and 7 are all relatively prime in pairs, the Chinese Remainder Theorem tells us that WebExample 1.2.
