What is HCF?

HCF:

A common factor of two or more numbers is a factor that is shared by the numbers. The highest common factor (HCF) of those numbers is found by finding all common factors of the numbers and selecting the largest one.

For example,

8 and 18 have common factors of 1 and 2.

The highest common factor of 8 and 18 is therefore 2.
