Prime number, an Epic card

The card carries these facts from its Wikipedia article.

• A natural number greater than 1 that is not prime is called a composite number.
• For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.
• However, 4 is composite because it is a product in which both numbers are smaller than 4.
