## Prime Numbers

A prime number is a positive integer having exactly two factors, i.e. 1 and the number itself. If p is a prime, then its only factors are necessarily 1 and p itself. Any number that does not follow this is termed a composite number, which can be factored into other positive integers.

## Prime number

A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

## List of prime numbers

A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid’s theorem, there are an infinite number of prime numbers. Subsets of the prime numbers may be generated with various formulas for primes.

A Prime Number is: a whole number above 1 that cannot be made by multiplying other whole numbers (if we can make it by multiplying other whole numbers it is a Composite Number) Here we see it in action: 2 is Prime, 3 is Prime, 4 is Composite (=2×2), 5 is Prime, and so on. Here is a list of all the prime numbers up to 1,000:.

## Prime Numbers

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. For example, 4 is a composite number because it has three positive.

## Prime Number Definition (Illustrated Mathematics Dictionary)

A whole number above 1 that can not be made by multiplying other whole numbers. 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).
