Exercise: the chinese remainder theorem for rings let $r$ be a ring and $i$ and $j$ be ideals in $r$ such that $i+j = r$ (a) show that for any $r$ and $s$ in $r$, the system of equation.

We may then use the theory of the chinese remainder theorem to conclude that a solution is:, where simplifying, we get, which we may take a=1, which we may take b=4, which we may take c=6 hence, x = 1(5)(7)+4(3)(7)+6(3)(5) = 209 is a solution.

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. Chinese remainder theorem el lady the chinese remainder theorem involves a situation like the following: we are asked to nd an integer x which gives a remainder of 4 when divided by 5, a remainder of 7 when.

• Instead the chinese remainder theorem (and associated algorithm) allows one to deduce x mod (p q) from a knowledge of x mod p and x mod q arithmetic mod p should be done mod (p-1) in an exponent, because a p-1 mod p = 1 (fermat's theorem) thus we can use the simpler calculation: v 1 = c d mod (p-1) mod p and v 2 = c d mod (q-1.
