The GCF is 9.
36 18,2 9,2,2 3,3,2,2 54 27,2 9,3,2 3,3,3,2 2 x 3 x 3 = 18, the GCF
8 4,2 2,2,2 18 9,2 3,3,2 The GCF is 2.
The lowest common factor of any set of positive integers is 1.
Since 18 is a factor of 72, it is automatically the GCF.
The greatest common factor of 18 21 and 42 is 3.
The GCF of 18 and 9 is 9.Since 9 is a factor of 18, it is automatically the GCF.
Since 18 is a factor of 80, it is automatically the GCF.
Since 9 is a factor of 18, it is automatically the GCF of this problem.
6, is the greatest common factor of 12 and 18.
Since 9 is a factor of 18, it is automatically the GCF.
The GCF of 18, 36, and 80 is 18. Since 18 is a factor of 36 and 80, it is automatically the GCF.
Since 18 is a factor of 216, it is automatically the GCF.
