Preamble:
% this is the default PlanetMath preamble. as your knowledge
% of TeX increases, you will probably want to edit this, but
% it should be fine as is for beginners.
% almost certainly you want these

\usepackage{amsmath}
\usepackage{amsfonts}
% used for TeXing text within eps files
%\usepackage{psfrag}
% need this for including graphics (\includegraphics)
%\usepackage{graphicx}
% for neatly defining theorems and propositions
%\usepackage{amsthm}
% making logically defined graphics
%\usepackage{xypic}

Content:
| If there was only a finite amount of primes then there would be some largest prime $p$. However $p!+1$ is not divisible by any number $n\leq p$ greater than one, so $p!+1$ cannot be factored by the primes we already know and there must be some prime greater than $p$. Thus there are infinitely many primes. |
