What are all the factors of 12?

In working as an ASVAB tutor, I emphasize the importance of being able to identify the factors of a number.  Knowing factors of a number is helpful in reducing fractions and determining which numbers are prime and which are composite.  Many people have a difficult time in reducing fractions and being able to figure out the factors of numbers makes reducing fractions easier.

Do you know how to find the factors of a number?
