When you multiply two or more numbers together the numbers that are multiplied together are known as factors of the final number. The number one is always a factor of any number and any number is always a factor of itself. Factors can be composite numbers or prime numbers. An example would be 4×3=12, two factors would be 4 and 3 since they both go evenly into 12 but the other factors would be 1, 2, 6, and 12. Therefore, 12 has 6 total factors.
