No.
Every even number has a factor of 2.
So any two even numbers share 2 as a factor.
So the greatest common factor has to be at least 2.
No, 2 is a common factor of all even numbers but not necessarily the greatest common factor. Take 40 and 32: 40:1,2,4,5,8,10,20,40 32:1,2,4,8,16,32 8 is the greatest common factor of these two even numbers.
