# What is the notation for set of prime factors of a number?

Is there a notation for the set of prime factors of a number, or set of factors of a number?

Essentially, $\operatorname{Spec} \mathbb{Z}/(n)$. –  Zhen Lin Feb 20 '13 at 9:09

Not really. Feel free to introduce your own notation at the beginning of whatever you're writing!
