The first common factor of any set of integers is 1.

Get the greatest common factor first. For example, you might use Euclid's Algorithm - the first step is that the greatest common factor of 5030 and 100 is the same as the greatest common factor of 100 and 30 (where 30 is the remainder of the division of 5030 / 100). Once you get the greatest common factor, the common factors of the two numbers are simply all the factors of this greatest common factor.
The only common factors are 1 and 2.
Most Common Factor, Greatest Common Factor, Highest Common Factor... all the same thing.
537 multiplied by 78 is 41,886.
1074
The first common factor is 1. The next (and only other common factor, their highest common factor) is 2.
The first common factor of any set of integers is 1.

Factor out the Greatest Common Factor.
Get the greatest common factor first.

This is a question that cannot be answered. First, 64 is not a prime number. Second, the greatest common factor is the factor that two or more numbers have in common. There is no greatest common factor of a single number, such as 64.
The first common factor of any set of integers is 1.
The factor pairs of 1074 are: 1 x 1074 2 x 537 3 x 358 6 x 179
Since 26 is a factor of 104, it is automatically the GCF.
