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

1 is a contested prime number, as a prime number is divisible by 1 and itself, and 1 is itself. (1), 2, 3, 5, 7, 11, 13, 17, 19, 23

A prime number is a number that is only evenly divisible by 1 and itself, since 11 and 17 both divide equally (no remainder) into 187 - it is not prime.

17

357 is not a prime number. Its positive integer factors are: 1, 3, 7, 17, 21, 51, 119, 357
