Question

If you multiply two prime numbers, will the result be prime or composite?

Answer 1

It can never be a prime number.

Explanation:

This is because the product of the two prime numbers are divisible by those two numbers, therefore going against the definition of a prime number. For example 3 and 5 are prime numbers and their product is 15. 15 can be divided by 3 and 5 so it is not a prime number.
