Cryptography Computer Security Greatest Common Divisor Assignment Instructions In software, implement the Euclidean algorithm to find the greatest common divisor of any two positive integers. It should implement the pseudocode provided in the text. It should allow the user to enter two integers. Your program should output the intermediate values of q, r1, r2 for each step and should return the greatest common divisor. Challenge component: Allow the user's input to be zero as well as the positive integers. Provide...

IN PYTHON Write a recursive function for Euclid's algorithm to find the greatest common divisor (gcd) of two positive integers. gcd is the largest integer that divides evenly into both of them. For example, the gcd(102, 68) = 34. You may recall learning about the greatest common divisor when you learned to reduce fractions. For example, we can simplify 68/102 to 2/3 by dividing both numerator and denominator by 34, their gcd. Finding the gcd of huge numbers is an...
We discuss the Euclidean algorithm that finds the greatest common divisor of 2 numbers u and v. We want to extend and compute the gcd of n integers gcd(u1,u2,….un). One way to do it is to assume all numbers are non-negative, so if only one of if uj≠0 it is the gcd. Otherwise replace uk by uk mod uj for all k≠j where uj is the minimum of the non-zero elements (u’s). The algorithm can be made significantly faster if one...
