A factor is a number that can evenly be divided into another number. Any number can be divided by one and itself. Numbers that can only be divided by one and themselves are called prime numbers. The number one and the number itself are factors of the number.
Some numbers have more factors than one and itself. Below is a chart of those numbers up to 100 and the other factors besides one and the number itself for the number. In each row the number. Remember, in each case, one and the number itself are also factors.
