When any number is multiplied by one it is equal to itself. A Prime number can only be the product of 1 multiplied by itself, and of no other numbers. Example: 1x3=3 1x5=5

Is the product of 2 numbers a prime number?

The product of two numbers could be either a composite number or a prime number. If one of those numbers is 1 and the other is a prime number, the result is that prime number. If neither number is 1, the product of the two numbers will be a composite number. If one of those numbers is 1 and the other is not a prime number, the product will not be a prime number. So, in most cases, it will be a composite number.
