Prime numbers are numbers greater than 1 that only have two factors, 1 and the number itself. This means that a prime number is only divisible by 1 and itself. If you divide a prime number by a number other than 1 and itself, you will get a non-zero remainder. Numbers that have more than 2 factors but finite number of factors are known as composite numbers. A prime number can be defined as a natural number greater than 1 whose only factors are 1 and the number itself. A prime number is a positive integer greater than 1 that cannot be written as a product of two distinct integers which are greater than 1. In the third century B. Step 1: Make a hundreds chart. Write all the natural numbers between 1 to using 10 rows and 10 columns. Step 3: Encircle 2 and cross out all its multiples such as 4, 6, 8, 10, and so on as they are not prime.

Twin-Primes: A pair of prime numbers are known as twin primes if there is only one composite number between them. Composite Numbers.

Prime numbers are natural numbers that are divisible by only 1 and the number itself. In other words, prime numbers are positive integers greater than 1 with exactly two factors, 1 and the number itself. Some of the prime numbers include 2, 3, 5, 7, 11, 13, etc. Always remember that 1 is neither prime nor composite. Also, we can say that except for 1, the remaining numbers are classified as prime and composite numbers. All prime numbers are odd numbers except 2, 2 is the smallest prime number and is the only even prime number.

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. The first primes are listed below, followed by lists of notable types of prime numbers in alphabetical order, giving their respective first terms. The following table lists the first primes, with 20 columns of consecutive primes in each of the 50 rows. There are known formulae to evaluate the prime-counting function the number of primes below a given value faster than computing the primes.

Prime numbers cannot be made by multiplying other smaller whole numbers. We say that a prime number has exactly 2 factors, which are the number 1 and the number itself. Apart from 2 and 5, the other prime numbers only end in a 1, 3, 7 or 9. A number is not prime if it is in the times table of another number.
