A. The largest number that goes into both 18 and 66 is 6. B. Using the step approach, 18 goes evenly into 66 three times to equal 54, leaving a remainder of 12. 12 goes into 18 one time, leaving a remainder of 6. 6 goes into 12 2 times, leaving a remainder of 0. So the last divisor, 6, is the greatest common divisor. Divide 18/66 by 6/6 which equals 3/11 reduced to lowest terms.
