## Note

In reference to the comment, there is a very standard notation denoting coprimeness:

- If integers $a$ and $b$ are coprime, we say $\text{gcd}(a,b)=1$ or even more briefly as $(a,b)=1$.

(Above post made by TruXus: TruXus's talk page, sometime 22nd August.)

I reiterate the argument made in conjunction with the Definition:Divisor Notation question, and add the following:

- a) $\gcd (a,b)=1$ is pointlessly long and unwieldy.
- b) $(a,b)=1$ is too riddled with ambiguity, as $(a,b)$ already has far too many uses. And it's nearly as unwieldy as the notation above.
- c} $\perp$ is convenient, short and memorable.

So $\perp$ is the preferred method, on this website, of denoting "is coprime to". --prime mover 14:20, 23 August 2011 (CDT)
