You need at least two numbers to find a GCF.
The Greatest Common Factor (GCF) is: 6
It is 11.
The highest common factor of 102 and 132 is 6.
The common factors are: 1, 11
The GCF is 12.
The highest common factor of the numbers 132 and 60 is 12.
The GCF of 132 and 198 is 66. The factors of 132 are 2x66=2x2x3x11, The factors of 198 are 198= 3x66=2x11x3x3 The GCF is 66.
The highest common factor of 102 and 132 is 6.
The factors of 132 are 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132. For them to be common, they need to be compared to another set of factors.
132 factors into 4 X 3 X 11 and 84 factors into 4 X 3 X 7. Therefore, their highest common factor is 4 X 3 = 12.
The common factors of 44 and 132 are 1, 2, 4, 11, 22 and 44.
factors of 60 are :- 1, 2, 3, 4, 5, 6, 10, 12, 15, 30 and 60 factors of 132 are :- 1, 2, 3, 4, 6, 11, 12, 22, 44, 66, 132 The highest factor found in both lists is 12
The factors of 132 are 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132. For them to be common, they need to be compared to another set of factors.
