Web3.7 The Chinese Remainder Theorem. We have taken some pains to note that Zn is not a subset of Z , and in particular that Zn = {[0], [1], …, [n − 1]} is not the same as {0, 1, …, n − 1}. The two sets certainly are closely related, however; [a] = [b] if and only if a and b have the same remainder when divided by n, and the numbers in {0 ... WebChinese Remainder Theorem One of the useful features of the Chinese remainder theorem is that it provides a way to manipulate (potentially very large) numbers mod M, in terms Of tuples Of smaller numbers. This can be useful when M is 150 digits or more. However note that it is necessary to know beforehand the factorization Of M.

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.
