What is the greatest common factor shared by 100 and 30?
the greatest common factor is 4. 2 and 4 are the only common factors of 100 and 24.
100 has factors 1,2,4,5,10,20,25,50,100. 378 has factors 1,2,3,6,7,9,14,18,21,27,42,63,126,189,378. 2 is the greatest common factor.

Common factors of 34 and 100 are: 1 and 2.
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.
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 100, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. Examples: The common factors of 35 and 100 are 1 and 5; the greatest common factor is 5. The common factors of 78 and 100 are 1 and 2; the greatest common factor is 2. The common factors of 100 and 625 are 1, 5, and 25; the greatest common factor is 25.
