The GCF helps in simplifying fractions and the LCM helps in adding and subtracting them.
When doing fractions it is the greatest common factor (GCF) and the least common multiple (LCM). You want the GCF when you are reducing fractions to their simplest form. When changing the denominators to a common one, you want the LCM.
The greatest common factor is used to reduce fractions.
Finding the greatest common factor helps when you are reducing fractions.
