To identify whether a number is prime or composite, look at its factors. A Prime number has exactly two factors: one and itself. A composite number has more factors and can be written as the product of prime numbers.
For example:
Factors of 17: 1 and 17 so 17 is prime.
Factors of 102: 1, 2, 3, 6, 17, 34, 51 and 102 so 102 is composite. It can be expressed as the product of prime numbers by prime factoring: 2 x 3 x 17
