What is the greatest factor for 2 and 3

The greatest common factor of 2 and 3 is 1. This is because 2

and 3 are prime numbers, that is, they only have themselves and one

as factors. NOTE: Any time that one of the numbers is a prime

number and the other is not a multiple of that prime number, the

greatest common factor is 1.

Another way to approach this, especially with larger numbers

(but this makes a good example) is to look at the difference

between 2 and 3, which is 1. The greatest common factor of two

numbers cannot be larger than the difference between the two

numbers and must be a factor of the difference. If the difference

is 1, the greatest common factor is 1.
