WebThe greatest common divisor has many practical applications ranging from simplifying fractions and number theory to encryption algorithms. The greatest common divisor … WebFor any a;b 2Z, the set of common divisors of a and b is nonempty, since it contains 1. If at least one of a;b is nonzero, say a, then any common divisor can be at most jaj. So by a flipped version of well-ordering, there is a greatest such divisor. Note that our reasoning showed gcd.a;b/ 1. Moreover, gcd.a;0/ Djajfor all nonzero a.

WebProve B ́ezout’s theorem. (Hint: As in the proof that the Eu- clidean algorithm yields a greatest common divisor, use induction on the num- ber of steps before the Euclidean algorithm terminates for a given input pair.) Bezout's theorem: Let a and b be integers with greatest common di- visor d. The key to finding the greatest common divisor (in more complicated cases) is to use the Division Algorithm again, this time with 12 and r. We now find integers q2 and r2 such that 12 = r ⋅ q2 + r2. What is the greatest common divisor of r and r2 ? Answer The Euclidean Algorithm
