Least Common Multiple (LCM) and Greatest Common Factor (GCF)
Introduction
If you "hate" fractions, this is the place for you! The Least Common Multiple (LCM) and the Greatest Common Factor (GCF) are two great ways to help students overcome their fear of fractions. Once you learn the techniques for each of these methods, you will begin to "like" fractions; at least a little more than you did before. Did you know that we use fractions everyday in life? We all eventually buy things using money and the amounts are fraction amounts, as well as the change we get back. Learning the LCM and the GCF can help you solve complex real world problems, can help you in transactions with money, and can help you manipulate numbers, percents and our feared topic of fractions. You can even use our trustworthy piece of technology; the "calculator", to find the LCM and GCF of numbers. A quick way to identify the LCM of two or more numbers is that it is larger than or equal to the given numbers and the quick way to identify the GCF of two or more numbers is that it is smaller than or equal to the given numbers. Come learn to "like" fractions with these two methods!
