THE CHINESE REMAINDER THEOREM - UCONN

The Chinese remainder theorem says we can uniquely solve any pair of congruences that have relatively prime moduli. Theorem 1.1. Let m and n be relatively prime positive integers. For any integers a and b, the pair of congruences x a mod m; x b mod n

The Chinese Remainder Theorem - ramanujan.math.trinity.edu

The Chinese remainder theorem (CRT) asserts that there is a unique class a+ NZ so that xsolves the system (2) if and only if x2a+ NZ, i.e. x a(mod N). Thus the system (2) is equivalent to a single congruence modulo N. Although we only proved one implication, one can actually show that the …

Historical development of the Chinese remainder theorem

The Chinese Remainder Theorem 291 where a, b, c are natural numbers, was the same as the congruence ax ~- b (mod c). Therefore the system of congruences in Example 2 may be converted into 100x ~ 32 (mod 83) ~ 70 (rood 110) ~ 30 (mod 135), and that in …
