Answer

GCF of 2 and 6 is

(Two)

Finding GCF for 2 and 6 using all factors (divisors) listing

The first method to find GCF for numbers 2 and 6 is to list all factors for both numbers and pick the highest common one:

All factors of 2: 1, 2

All factors of 6: 1, 2, 3, 6

So the Greatest Common Factor for 2 and 6 is 2

Finding GCF for 2 and 6 by Prime Factorization

The second method to find GCF for numbers 2 and 6 is to list all Prime Factors for both numbers and multiply the common ones:

All Prime Factors of 2: 2

All Prime Factors of 6: 2, 3

As we can see there is only one Prime Factor common to both numbers. It is 2

So 2 is the Greatest Common Factor of 2 and 6
