### What is a prime number times a prime number?

A prime number times a prime number is a composite number.
Since prime numbers, except for 2, are odd numbers, a prime
number times a prime number is usually an odd number. It will only
be an even number if one of the prime numbers is 2.
A prime number times a prime number will be a number with four
factors unless both prime numbers are the same, in which case it
will be a square number with only three factors.
