2024年7月30日 · Chinese Remainder Theorem is a mathematical principle that solves systems of modular equations by finding a unique solution from the remainder of the division. It is used in cryptography and computer science for efficient computation.
2024年5月24日 · Chinese Remainder Theorem states that there always exists an x that satisfies given congruences. Let num [0], num [1], …num [k-1] be positive integers that are pairwise coprime. Then, for any given sequence of integers rem [0], rem [1], … rem [k-1], there exists an integer x solving the following system of simultaneous congruences.

Formally stated, the Chinese Remainder Theorem is as follows: Let be relatively prime to . Then each residue class mod is equal to the intersection of a unique residue class mod and a unique residue class mod , and the intersection of each residue class mod with a residue class mod is a residue class mod . This means that if we have we can deduce t...
If , then and differ by a multiple of , so and . This is the first part of the theorem. The converse follows because and must differ by a multiple of and , and . This is the second part of the theorem.
Much like the Fundamental Theorem of Arithmetic, many people seem to take this theorem for granted before they consciously turn their attention to it. Its ubiquity derives from the fact that many results can be easily proven mod (a power of a prime), and can then be generalized to mod using the Chinese Remainder Theorem. For instance, Fermat's Litt...
In order to solve a system of n congruences, it is typical to solve the first two, then combine that with the third, and so on. So, it suffices to know how solve a system of 2 congruences. Let the system be (where and are relatively coprime): Then if we find one value such that satisfies the system, then the solution set consists of . To find such ...
Suppose one tried to divide a group of fish into , and parts instead and found , and fish left over, respectively. Any number with remainder mod must be odd and any number with remainder mod must be even. Thus, the number of objects must be odd and even simultaneously, which is a contradiction. Thus, there must be restrictions on the numbers to ens...
2023年10月16日 · The Chinese Remainder Theorem (which will be referred to as CRT in the rest of this article) was discovered by Chinese mathematician Sun Zi. Formulation. Let m = m 1 ⋅ m 2 ⋯ m k , where m i are pairwise coprime. In addition to m i , we are also given a system of congruences. {a ≡ a 1 (mod m 1) a ≡ a 2 (mod m 2) ⋮ a ≡ a k (mod m k)

In mathematics, the Chinese remainder theorem states that if one knows the remainders of the Euclidean division of an integer n by several integers, then one can determine uniquely the remainder of the division of n by the product of these integers, under the are
