Gcd a bc 1

Web(a)Suppose gcd(a;b) = 1. (i)Show that if a divides the product bc, then a must divide c. I give two proofs here, to illustrate the di erent methods. Proof 1: Using only ch. 6 results. Since gcd(a;b) = 1, we have ax+ by = 1 for some x;y … WebNov 13, 2024 · Example 4.2. 1: Find the GCD of 30 and 650 using the Euclidean Algorithm. 650 / 30 = 21 R 20. Now take the remainder and divide that into the original divisor. 30 / 20 = 1 R 10. Now take the remainder and divide that into the previous divisor. 20 / 10 = 2 R 0. Since we have a remainder of 0, we know that the divisor is our GCD.

WebMultiplying as + ct = 1 by b reveals bas + bct = b. Substitute into the expression for b into (2) to get [bas + bct]u + cv = 1. That rearranges to (ab)(su) + c(btu + v) = 1; i.e., gcd(ab,c) = 1. (ii) If gcd(ab,c) = 1, then there exist integers u, v such that (ab)u + cv = 1. i.e., a(bu) + cv = 1 and b(au) + cv = 1. Therefore gcd(a,c) = gcd(b,c) = 1. Weba, and GCD(b;c) = 1, then bc a.
