I am writing an article in LaTeX 2e. Part of the article describes the Sieve of Eratosthenes, and I want to show examples of how multiples of a prime are removed from the sieve by showing them in a strikethrough font. How do I create a strikethrough font in LaTeX 2e?
I’m not quite sure what you mean with creating a strikethrough font. However, for striking through text horizontally see:

So with the ulem package this is:
\usepackage[normalem]{ulem}
\sout{Hello World}
With the soul package this is:
\usepackage{soul}
\st{Hello World}
enter image description here
The ulem package seems more up to date so I would use that.
