The GCF is 2.
Since 11 is a factor of 22, it is automatically the GCF.
Answer:1,2,11,and22
The GCF is 1.
66
The common factors are: 1, 2
1, 11 1, 2, 11, 22
No, 18 is a multiple of 6. 6 is a factor of 18.
72 is not a factor of 18; 18 is a factor of 72.
18 is the greatest factor of 18.
No, 18 is a multiple of 3. 3 is a factor of 18.
Since 18 is a factor of 90 and it is the largest factor of itself, the greatest common factor of 18 and 90 is 18.Since 18 is a factor of 90, it is automatically the GCF.
