Factoring Integers
Factoring Integers
To factor an integer, simply break the integer down into a group of numbers whose product equals the original number. Factors are separated by multiplication signs. Note that the number 1 is the factor of every number. All factors of a number can be divided evenly into that number.
Example 1: Factor the number 3.
Answer:
Since 3 x 1 = 3, the factors of 3 are 3 and 1.
