A prime number is a natural number greater than 1 that has no positive integer divisors other than 1 and itself For example 5 is a prime number because it has no positive divisors other than 1 and 5 In contrast to prime numbers a composite number is a positive integer greater than 1 that has more than two positive divisors Example 5 is a prime number We cannot multiply 2 3 or 4 together to make 5 Only 1 5 works but we said to use other whole numbers Example 6 can be made by 2 3 so is NOT a prime number it is a composite number All whole numbers above 1 are either composite or prime Prime Numbers and Composite Numbers Watch on See
Examples The following are the first five prime numbers 2 1 2 3 1 3 5 1 5 7 1 7 11 1 11 The number 1 has only one factor 1 1 1 so it is not a prime number It is also not a composite number The natural numbers greater than 1 that aren t prime numbers are called composite numbers Prime numbers are numbers that have only 2 factors 1 and themselves For example the first 5 prime numbers are 2 3 5 7 and 11 By contrast numbers with more than 2 factors are call composite numbers Created by Sal Khan

A prime number is a number that has exactly two factors itself and 1 There are an infinite number of prime numbers Numbers that have more than two factors are called composite As Wolfram MathWorld explains a prime number also known simply as a prime is a positive number greater than 1 that can only be divided by one and itself It needs to be divisible by two numbers With that definition of prime numbers in mind the number 1 isn t a prime number
Prime Number Composite Number It has exactly two factors It has more than two factors It can be divided evenly only by 1 and the number itself For example 2 is divisible only by 1 and 2 It can be divided evenly by all its factors For example 4 is divisible by 1 2 and 4 Examples 11 13 19 37 41 etc Examples Is 8 a Prime Number No because it can be made by 2 4 8 Is 73 a Prime Number Yes as no other whole numbers multiply together to make it Calculator Is It Prime Find out if a number is Prime or not works on numbers up to 4 294 967 295 You can also try this Prime Numbers Activity
