Question

If a,b=d, prove that ad,bd=1.​

Answer 1

Answer:

Proof.

Let c = (a/d, b/d). Then c | a/d, and so cd | a. Also c | b/d, and so cd | b.

My question is, did this happen because of this simple algebra? ie. c | a/d So cx = a/d for some integer x then cx/d = a

Next step of proof.. Thus, cd is a common divisor of a and b. Therefore, cd <= d, which implies c = 1.

Answer 2

Answer:

is that a.b or a,b??
