This question doesn't lend itself well to plain text, so I LaTeX'd and screenshotted it. I'll do my best with the alt text.

@me you will see a few variations on this if you look around. I would write it like this, but you can write basically anything unambiguous. You see notation like "a | n" or "g ∈ G" under summation symbols to represent summation over the divisors of n and elements of G, respectively, so it's pretty casual.
