Least Common Multiple (LCM) & Greatest Common Factor (GCF)

The Greatest Common Factor, or GCF for short, of a list of numbers is the largest factor that divides into all of the numbers evenly. Example: The GCF of 20 and 30 is 10 since 10 divides into 20 evenly 2 times and 10 divides into 30 evenly 3 times. ................
