B1 a. Let x := 3C1 + 1 and let y := 5C2 + 1. Use the Euclidean algorithm to determine the GCD (x, y), and we denote this integer by g. b. Reverse the steps in this algorithm to find integers a and b with ax + by = g. c. Use this to find the inverse of x modulo y. If the inverse doesn't exist why not?...

Notes: Suppose (a, n) = 1, then there is an integer s such that as = 1 (mod n). This s is called the inverse of a, i.e., a-1 (mod n). The way to find the inverse is asfollows:1) Use the extended Euclidean algorithm to find s and t such that as + nt = 1;2) Then a-1(mod n) = s.In the lecture, we gave an example to find 37-1(mod 121) in three steps.Step-1: use Euclidean algorithm to get the...

PROBLEM 1 For each of the following pairs of integers, use the Euclidean Algorithm to find ged(a,b), and to write gcd(a,b) as a linear combination of a and b, i.e. find integers m and n such that gcd(a,b) = am + bn. (a) a = 36, b = 60. (b) a = 12628, b = 21361. (c) a = 901, b = -935. (d) a = 72, b = 714. (e) a = -36, b = -60.
