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 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.
Since 9 is a factor of 18, it is automatically the GCF of this problem.
The greatest common factor of 18 21 and 42 is 3.
6, is the greatest common factor of 12 and 18.
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.
