It is: 13
The common factors are: 1, 2, 3, 4, 6, 12.

The common factors of 12 and 56 are: 1, 2, and 4
the highest common factors of 8 and 12 is 4!!
1 and 3.
1 and 3
The only common factors are: 1, 3
The GCF is 3.
Since 13 is a factor of 39, all of its factors are common.
Yes. The factors of 24 are 1, 2, 3, 4, 6, 8, 12, and 24. The factors of 39 are 1, 3, 13, and 39. The common factors are 1 and 3, so the greatest common factor is 3.
The common factors of 13 and 39 are: 1 and 13
The common factors of 39 and 91 are: 1 and 13
The common factors of 27 and 39 are 1 and 3
Any of 39's factors can be common.
The common factors of 51 and 39 are 1 and 3.
39 has a couple factors: 1, 3, 13, 39. Its greatest factor would be 39. HOWEVER, it doesn't have a common factor. You need two numbers to find what their greatest common factor is. For instance: 8 and 12. 8 has 1,2,4,8 and 12 has 1,2,3,4,6,12. The factors they have in common are 2 and 4, with 4 being their GCF. So 39 cannot have a common factor unless there is another number!
