A number that is not a prime number is called a composite number because it can be made by multiplying prime numbers together. For example, 6 is a composite number that is the product of multiplying the prime numbers 2 and 3 together.

Consecutive prime numbers are two prime numbers that are next to each other, with no other prime numbers in between. For example, 3 and 5 are consecutive prime numbers.

Prime factorization is writing a composite number as a product of prime numbers.

17 is a prime number. 8 and 12 are not prime numbers.

Numbers with only two factors, the number itself and one, are called prime numbers. Examples of prime numbers are 2 (which is the only even prime number) and 17.
