Some possible answers are:
The LCM is useful when adding or subtracting fractions. It is also useful when finding the number of times two given numbers will overlap; for example, if you plant red flowers every 2 feet and yellow flowers every 3 feet, at what distances would you plant both color of flowers?
The GCF is useful when simplifying fractions.
