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.

What is the greatest common factor of 18 and 51?
The greatest common factor of 18 and 51 is 3.18 ÷ 3 = 651 ÷ 3 = 17Method: One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 18 are 1, 2, 3, 6, 9, and 18.The factors of 51 are 1, 3, 17, and 51.The common factors are 1 and 3. Therefore, the greatest common factor is 3.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 18 are 2, 3, and 3.The prime factors of 51 are 3 and 17.The prime factors in common are a single 3, so the greatest common factor is 3.The greatest common factor of 51 and 18 is 3
