WebFinal answer. 1. Let a,b,c ∈ N. Prove that if gcd(a,b) = 1 and gcd(a,c)= 1, then gcd(a,bc) = 1. [HINT: First check that the statement is true if any of a,b, or c is equal to 1 . Then, for the case where a > 1,b > 1, and c > 1, consider unique prime factorizations.] 2. WebUnderstanding the Euclidean Algorithm. If we examine the Euclidean Algorithm we can see that it makes use of the following properties: GCD (A,0) = A. GCD (0,B) = B. If A = B⋅Q + …
