There cannot be a greatest common factor (GCF) of just one number. To be common there need to be at least two numbers. If you find all the factors of two or more numbers, and you find some factors are the same ("common"), then the largest of those common factors is the Greatest Common Factor.

What is the greatest common factor of 21 and 99?
The greatest common factor of 21 and 99 is 3. 21's factors are 1,3,and 7 99's factors are 1,3,9,11 33 (there may be more factors of 99). The highest factor that both number have in common are 3.
What is the HCF of 99?
The Highest Common Factor (HCF) of 99 is 99. This is because 99 is a prime number, meaning it only has two factors: 1 and 99. Since there are no other common factors between 99 and any other number, the HCF remains 99.

What is the highest common factor of 225 and 99?
The GCF is 9.
What is the highest common factor of 63 and 99?
The highest common factor (HCF) of 63 and 99 is 9. To find the HCF, you can list out the factors of each number and then identify the highest number that appears in both lists. The factors of 63 are 1, 3, 7, 9, 21, and 63, while the factors of 99 are 1, 3, 9, 11, 33, and 99. The highest number that appears in both lists is 9, making it the HCF of 63 and 99.
What is the Highest Common Factor between 99 and 132?
99 = 3 * 3 * 11132 = 2 * 2* 3* 11hcf = 3 * 11hcf =33
What is the greatest common factor for 3 and 99?
It is not possible to give a sensible answer to this question. The highest common factor (HCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!
