Mastering the GCF helps you to reduce fractions. Mastering the LCM helps you to add and subtract fractions. Let's look down the road. What else is about mastering the manipulation of numbers and fractions and percentages? Money. Every business uses that in some form or another.

GCF is used to simplify fractions, especially rates. For example, if you drive 480 miles using 20 gallons of gas, you can use GCF to simplify the fraction to a unit rate.

The GCF of 20 and 480 is 20. 480/20 can be simplified to 24 miles per 1 gallon of gas.
