How do you calculate the greatest common factor?
Given two whole numbers, subtract the smaller number from the larger number and note the result. Repeat the process subtracting the smaller number from the result until the result is smaller than the original small number. Use the original small number as the new larger number. Subtract the result from Step 2 from the new larger number.
