The common factors of 30 and 100 are 1, 2, 5 and 10.
The common factors are: 1, 2, 5, 10.
If that's 30, 50, and 100, the common factors are 1, 2, 5, 10
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.
1, 2, 5, 10
1, 2, 5 and 10
1, 2, 5, 10
1, 2, 5, 10
They are: 1 2 5 and 10
The common factors of 30, 50, and 100 are 1, 2, 5 and 10.
The common factors are: 1, 2, 5, 10
