Solving simultaneous congruences

WebThe Chinese remainder theorem is widely used for computing with large integers, as it allows replacing a computation for which one knows a bound on the size of the result by several similar computations on small integers. The Chinese remainder theorem (expressed in terms of congruences) is true over every principal ideal domain. WebDecide whether the system has a solution (and if it does, nd all solutions) by solving the system for each prime factor separately. 1. n2 11 (mod 35) Working over each prime factor separately gives n2 1 (mod 5) and n2 4 (mod 7), so n = 1 (mod 5) and n = 2 (mod 7).
