GCF stands for Greatest Common Factor. The word 'common' is used when we compare two or more elements to see similarities or when something is equally shared by two or more things.
Let us consider an example:
What is common between a lion and a tiger?
1 - Both are wild animals
2 - Both are mammals
3 - Both are flesh eating animals
But we can't ask for similarities for a lion to itself.
So, we need at least two things to compare. We can't compare an element to itself to find similarities.
Similarly it is not possible to find GCF for one number only.
The term GCF is not defined for only one number.
You need at least two numbers to find a GCF.
The GCF is 6.
The GCF is 14.
The GCF is 12.
The GCF is 4.
The GCF is 14.
The GCF of 40 and 168 is 8.
The GCF is 14.
The GCF is 12.
14 is the GCF of 70, 98 and 168.
The GCF of 98, 154 and 168 is 14.
GCF(84, 168, 182) = 14
GCF(48, 168, 280) = 8.
