WebChinese Remainder Theorem Example. Find a solution to x 88 (mod 6) x 100 (mod 15) Solution 1: From the rst equation we know we want x 88 = 6k for some integer k, so x is of the form x = 88 + 6k. So from the second equation, we also want 88 + 6k 100 (mod 15), so we want 6k 12 (mod 15). Use the extended Euclidean Algorithm to nd that 15(1)+6( 2) = 3.

WebChinese remainder theorem, ancient theorem that gives the conditions necessary for multiple equations to have a simultaneous integer solution. The theorem has its origin in … 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.
