WebThe Chinese Remainder Theoremsays that certain systems of simultaneous congruences with dif-ferent moduli have solutions. The idea embodied in the theorem was known to the Chinese mathematician Sunzi in the 3rd century A.D. — hence the name. I’ll begin by collecting some useful lemmas. Lemma 1. Let mand a 1, ..., a n be positive integers ... Web§2The Chinese Remainder Theorem First let me write down what the formal statement of the Chinese Remainder Theorem. Theorem 2.1 (Chinese Remainder Theorem) Let m 1;:::;m k be pairwise relatively prime positive integers, and let M = m 1:::m k: Then for every k-tuple (x 1;:::;x k) of integers, there is exactly one residue class x (mod M) such ...
WebProblems on Chinese Remainder Theorem: Example 1: Find x, if possible, such that 2x ≡ 5 (mod 7), and 3x ≡ 4 (mod 8) Solution: First, we must know that 2 has an inverse modulo 7, namely 4. So we can write the first equivalence as x ≡ 4 · 5 ≡ 6 (mod 7). (Using the Chinese Remainder Theorem) Hence, we have that: x = 6 + 7k for some k ∈ Z.
