## Greatest Common Divisor

$\tuple {a, b}$

The notation for the greatest common divisor is commonly seen as:

$\tuple {a, b}$

However, as the $\tuple {a, b}$ notation is ambiguous, its use is deprecated on $\mathsf{Pr} \infty \mathsf{fWiki}$.

The $\LaTeX$ code for $\tuple {a, b}$ is \tuple {a, b} .
