What is the greatest common factor between 25 and 50?

Answer 1

(wild guess) 10

It is not possible to give a sensible answer to this question. The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question!

Answer 2

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 common factors or largest common factor for one number only.

Answer 3

Since 25 is a factor of 50, it is automatically the GCF.

Answer 4

50

25,2

5,5,2
