If the moduli were not coprime, then one or. We must now solve this system of equations: M c1 (mod n1) M c2 (mod n2) M c3 (mod n3) Assuming all three ns are coprime, the Chinese Remainder Theorem indicates that there is a solution for the system exists.

I make RSA encryption in python with private key and cannot decrypt in Java with public key.
