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. WebLet us solve, using the Chinese Remainder Theorem, the system: x 3 mod 7 and x 6 mod 19. This yields: x 101 mod 133. (There are other solutions, e.g. the congruence x 25 mod 133 is another solution of x2 93 mod 133.) Question 6. Show that 37100 13 mod 17. Hint: Use Fermat’s Little Theorem. Solution: First 37100 3100 mod 17 because 37 3 mod 17 ...
