The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100. For them to be common, they need to be compared to another set of factors.
49 and 100 share no common factors aside from 1.
Since 100 is a factor of 200, all of its factors are common.
1 and 5 are their only common factors.
The common factors are: 1, 2, 4
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.
The common factors of 58 and 100 are: 1, 2
49 and 100 share no common factors aside from 1.
The common factors of 24 and 100 are 1, 2 and 4
The common factors of 16 and 100 are 1, 2 and 4.
Common factors of 34 and 100 are: 1 and 2.
Common factors of 100 and 100 are: 1, 2, 4, 5, 10, 20, 25, and 50.
Since 100 is a factor of 200, all of its factors are common.
The common factors of 30 and 100 are 1, 2, 5 and 10.
The common factors of 10 and 100 are 1, 2, 5, 10
