33
Since 33 is a factor of 66, it is automatically the GCF.
The GCF of 66 and 99 is 33. This gives you 2 and 3 respectively. You cannot get any more common factors that impact the end figure.
Start with the factors of 99: 99 = 33 X 3 = 11 X 3 X 3. So {1, 3, 9, 11, 33, 99} are the factors of 99. Next find the factors for 66: 66 = 11 X 6 = 11 X 3 X 2. So {1, 2, 3, 6, 11, 22, 33, 66} are the factors of 66. Next find the common numbers of these two sets: {1, 3, 11, 33}. Since 33 is the largest of these numbers, it is the greatest common factor.
The common factors of 21 and 66 are 1 and 3. The factors of 21 are 1, 3, 7, and 21. The factors of 66 are 1, 2, 3, 6, 11, 22, 33, and 66. The common factors are 1 and 3. The greatest common factor is 3.
