The highest number that divides into both parts of the fraction is called the greatest common factor. If you are trying to simplify the fraction 8/12, you find that the greatest common factor is 4. Divide the numerator by 4 to get 2. Divide the denominator by 4 to get 2. Therefore, simplifying 8/12 leads you to the answer of 2/3.
