The Chinese Remainder Theorem
Proof: We are given that n divides (x+y)(x−y) but not (x+y) or (x−y) Hence one of p q must divide (x + y) and the other must divide (x − y) |

We first prove what is commonly known as the “Chinese remainder theorem” As an application this will let us quickly calculate φ(m) in terms of the prime |
Is Chinese remainder theorem unique?
At this point, since the moduli 3, 4, and 11 have the property that every two are relatively prime, the Chinese Remainder Theorem states that there is a unique solution to these congruences among the integers between 0 and 131 (here 3⋅4⋅11=132).
Chinese remainder theorem, ancient theorem that gives the conditions necessary for multiple equations to have a simultaneous integer solution.
The theorem has its origin in the work of the 3rd-century-ad Chinese mathematician Sun Zi, although the complete theorem was first given in 1247 by Qin Jiushao.
