Prime Number Charts

Below you’ll find our printable prime number charts. 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 formed by multiplying any two numbers other than 1 and itself.

The first few prime numbers are: 2, 3, 5, 7, 11, 13, 17, 19, and so on.

To determine whether a number is prime, you need to check if it has any divisors other than 1 and itself. If a number has divisors other than these, it is not prime; otherwise, it is prime.

We’ve included six different charts below to help your students learn what numbers are prime.
