Chinese remainder theorem explanation example
WebThe Chinese Remainder Theorem R. C. Daileda February 19, 2024 1 The Chinese Remainder Theorem We begin with an example. Example 1. Consider the system of simultaneous congruences x 3 (mod 5); x 2 (mod 6): (1) Clearly x= 8 is a solution. If ywere another solution, then we would have y 8(mod 5) and y 8(mod 6). Hence 5jy 8 and 6jy 8.

WebExample 1: Find the remainder when p (x): 3x 5 − x 4 + x 3 − 4x 2 + 2 is divided by q (x): x − 1. Solution: We will use the remainder theorem. We will substitute the zero of q (x) into the polynomial p (x) to find the remainder r. The zero of q (x) is x = 1. So the remainder, r = p (1) = 3 (1) 5 - (1) 4 + (1) 3 - 4 (1) 2 + 2 = 3 - 1 + 1 - 4 + 2 = 1 WebFeb 10, 2024 · Example: using the Chinese remainder theorem Say that your mom bought a few handfuls of sweets and would like to give them away to you and your three siblings. However, she knows all too well how her children hate when we give one more than the others, so she quickly counts the candies. Oh, bother!
