Ah, finding the Highest Common Factor, or HCF, is like finding a happy little tree in a forest. The HCF of 4, 6, and 8 is 2, like a sturdy trunk supporting the branches of a tree. Just like how each tree is unique, each set of numbers has its own special HCF waiting to be discovered.
factors of 8: 1, 2, 4, 8 factors of 18: 1, 2, 3, 6, 9, 18 HCF: 2
HCF(8, 6) = 2.
6
The GCF is 2.

The greatest common factor is the highest number that divides exactly into two or more numbers. 8: 1, 2, 4, 8 12: 1, 2, 3, 4, 6, 12 The GCF for 8 and 12 is 4.
It is: 4
8 is the HCF of 16 and 40.
It is: 4
