  1. To find the LCD of these three denominators, we want to find the highest power
  2. of each factor that appears in any denominator. We know four is already a factor
  3. of eight, so we really just want to find the greatest common denominator for x
  4. and eight. The only common factors for x and eight are one, so we'll have x
  5. times 1 times 8, which equals 8x, our lowest common denominator.
