      The Euclidean algorithm, applied to k and n, produces integers x and y for which kx + ny = 1. In (Z/nZ) the class of x is the inverse of the class of k. Example: See handout. What is the order of (Z/nZ) ? It is (n) = the number of pos. integers ≤ n which are relatively prime to n.

      The Euclidean Algorithm is a great example for the usage of the while-loop and is thus discussed in many introductory programming lectures. You will learn that a while-loop just as a do-while-loop are examples of indefinite loops which just means that number of runs is indefinite. (A for-loop, on the contrary, is a definite loop since the ...

      The Continued Fractions Form of the Euclidean Algorithm in . F x This is essentially the form of the algorithm found in Berlekamp’s text on algebraic coding theory. You do not need to know continued fractions to follow it. The idea is to follow the standard, thousands-of-years-old process of successive divisions, while making “side ...

      The Euclidean Algorithm is used to find the greatest common divisor between two numbers. It is the solution to Proposition VII.2 in Euclid’s Elements: “To find the greatest common measure of two given numbers not relatively prime”. The algorithm is based on the following lemma with two observations:

      Note that this can be found using the Euclidean Algorithm. Compute the private key, d, which is the multiplicative inverse of i.e., find an integer d with In general, solve for d in the equation The existence of d follows from the fact that if given two integers, a and b, where the then b is invertible (mod a) and b has a multiplicative inverse in.
