Question: how to find the gcf of the numerator and denominator?
Answer: To simplify completely, divide both numerator and denominator by the 60. Example: Write the fraction in simplest terms. We find the greatest common factor for the numerator and the denominator: 78 = 2 · 3 · 13 and 84 = 22 · 3 · 7 so the GCF(78, 84) = 2 · 3 = 6.
