What is a chart of prime numbers?

A chart of prime numbers is a chart that lists numbers that are only divisible by one and itself. A prime number can be even or odd, but it must be a whole number.

While it is only possible for one to be divided by itself, it is not considered a prime number. A prime number must be greater than one. Therefore, it must always be positive. Prime numbers are not rare, but they are more difficult to work with because they have no factors other than one and itself. A chart of prime numbers can be of any size; it is dependent on what is required for the mathematical situation.
