chinese remainder theorem word problems pdf
For example, if we know that the remainder of n divided by 3 is 2, the remainder of n divided by 5 is 3, and the remainder of n divided by 7 is 2, then without knowing the value of n, we can determine that the remainder of n divided by 105 (the product of 3, 5, and 7) is 23.
How to find multiplicative inverse in Chinese remainder theorem?
We can find the multiplicative inverse of b mod a if a and b are relatively prime (if not, the multiplicative inverse does not exist).
Since gcd(a, b) = 1, the extended Euclidean algorithm gives us s and t such that sa + tb = 1.
Taking mod a on both sides, we get that t = b−1 mod a.
