No, 18 is.

Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 18, 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 18 are 1, 2, 3, 6, 9, and 18. Examples: The common factors of 18 and 24 are 1, 2, 3, and 6; the greatest common factor is 6. The common factors of 18 and 81 are 1, 3, and 9; the greatest common factor is 9. The common factors of 18 and 54 are 1, 2, 3, 6, 9, and 18; the greatest common factor is 18.

The Greatest Common Factor (GCF) is: 9

To find the greatest common factor for any group of numbers you must make a list of all the factors for each number. The factors of 18 are: 1, 2, 3, 6, 9, 18 The factors of 9 are: 1, 3, 9 Therefore, the greatest common factor of 18 and 9 is 9.

Since 9 is a factor of 18, it is automatically the GCF of this problem.

The greatest common factor of 9, 18, and 27 is 9. Since 9 is a factor of both 18 and 27, it is automatically the GCF of the set.Factors of 9: 1, 3, 9Factors of 18: 1, 2, 3, 6, 9, 18Factors of 27: 1, 3, 9, 27GCF (9, 18, 27) = 9
