What is a prime number?
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In other words, a prime number cannot be split into equal groups or factored into smaller whole numbers. Numbers that have more than two factors are called composite numbers.
How to find prime numbers
One ancient method to find prime numbers is the Sieve of Eratosthenes: 1) List numbers from 2 to your limit. 2) Circle 2 and cross out all multiples of 2. 3) Circle the next remaining number (3) and cross out all its multiples. 4) Repeat for the next uncrossed number. The circled numbers that remain are all prime numbers.
Primes under 100
There are exactly 25 prime numbers under 100: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, and 97. The number 2 is the only even prime number.
