How are the concepts of the Greatest Common Factors (GCF), divisibility, and Lowest Common Multiple (LCM) used when computing fractions? Provide an example and demonstrate how the concepts are used. Participate in the discussion by adding anything to the explanation that your classmates may have omitted. Ask follow up and clarifying questions as necessary. GCF is an excellent tool to use when reducing fractions. The GCF is the “greatest common factor”. For example, here is an example of GCF: We have 3 and 6. The GCF is found like this: 3 - 1, 3 6 - 1, 2, 3 In these 2 numbers, the greatest common factor is 3, so it is the GCF. Now let’s pretend we had the fraction 3/6. This would help us to reduce the fraction. With divisibility, we can divide the top and bottom of the fraction by 3 and we get: 3/6 = (3/3)/ (6/3) = ½ So it would reduce to ½. LCM is also useful especially when adding, subtracting, dividing or multiplying fractions.
