... useful when adding and subtracting fractions. This is because the most efficient common denominator to choose is the lowest common multiple of the denominators – see study guide: Adding and Subtracting Fractions. In order to find lowest common multiples quickly it is important that you can factorise ...

... Solution by Leonard A. G. Dresel, Reading, England We shall find two solutions, namely a = 6, b = 9, c = 4, and a - 12, b - 9, c - 72, and show that these are the only solutions. Putting n = b in the given identity, we have Fb = HFb_a, so that 17 divides i^,, giving Z? = 9, 18, 27, ... . In fact, b ...
