Introduction to Number Theory : Euclids Algorithm

= 1. The integers modulo n. Let n be a positive integer. Two integers x and y are said to be congruent modulo n if x

Congruences

The next result says that two integers a and b are congruent modulo n if and only if a and b leave the same remainder when the division algorithm is

Counting modulo n and its time complexity

Repeated squaring algorithm. We compute ab in Zn by successive squaring. We write the exponent binary: b = (bk?1 b0)2. We create a sequence of commands X= ...

u Understand the concept of divisibility and the division algorithm. Two integers a and b are said to be congruent modulo n if (a mod n) = (b mod n).

Congruences

If n is an integer then a is congruent to b modulo n if and only if a and b have the same remainder when divided by n. Proof. By the division algorithm

Jan 25 2022 Implementing the GCD Algorithm in Perl and Python ... We will call two integers a and b to be congruent modulo n if a mod n = b mod n.

Lecture 25

we will only be interested in algorithms running in polynomial time; Modular exponentiation (i.e. computing ab mod N) can be done using O(
