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.
99 and 165's highest common factor is 33.
It is: 15

The Greatest Common Factor (GCF) is: 15
165 is.
The Highest Common Factor (HCF) of 165 and 150 is 15. To find the HCF, you can list out the factors of each number and identify the highest common factor. The factors of 165 are 1, 3, 5, 15, 33, 55, and 165. The factors of 150 are 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, and 150. The highest common factor between the two numbers is 15.
It is important to note that there is no such thing as a greatest common multiple - but as a lowest common multiple and a highest common factor.
The greatest common factor of the numbers 165 and 6 is 3.
