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.

Is the greatest common factor an odd number and even number is always even?
No. Odd numbers only have odd factors. They could not have an even factor in common.
Is the greatest common factor factor of a odd number and a even number always even?
No, the GCF of 6 and 7 is 1.
Is the greatest common factor of an even number and an odd number always even?
No. The GCF of 6 and 15 is 3.
Is the greatest common factor of two even numbers always two?
No, but it's always an even number.
Is the greatest common factor of an odd and even number always 1?
No, the GCF of an odd an even number is not always 1. Odd and even numbers can share factors other than 1. For example, the greatest common factor of 5 and 10 is 5.
Can the greatest common factor of an even number be an odd number?
No.
Is the Greatest common factor of an even number and an odd number even?
Never.
Is the greatest common factor an odd number and even number is always even?
No. Odd numbers only have odd factors. They could not have an even factor in common.
Is the greatest common factor of an odd number in even numbers always even?
No.
Is the greatest common factor factor of a odd number and a even number always even?
No, the GCF of 6 and 7 is 1.
Can two odd numbers have a greatest common factor that is an even number?
No. Because both numbers are even, they each have 2 as a factor. Even if they have a larger factor in common, it will be a multiple of 2, so the greatest common factor will be an even number.Yes. Two even numbers are each divisible by 2. The GCF must therefore always have two as one of its factors; this makes it even.
Can two even numbers have greatest common factor of 1?
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.
Will the greatest common factor of an odd and even number always be even?
No, always odd.
What is the greatest common factor of two consecutive even number?
The GCF is 2.
What even and odd number have a greatest common factor of 19?
19 and 38
Is the greatest common factor of any odd number and even number always even?
No, always odd.
What is the greatest common factor of 14b and 21ab?
The prime factors of 21 are 3 and 7.The prime factors of 14 are 2 and 7.The greatest common factor of 21 and 14 is 7.21ab and 14b also have another factor in common - b. So, the greatest common factor of 21ab and 14b would appear to be 7b . However, it is possible that a and 14 share a common factor of 2, in which case the greatest common factor of 21ab and 14b would be 14b.In summary, if a is an even number (i.e. having a factor of 2), the greatest common factor is 14b.If a is not an even number, the greatest common factor is 7b.gcf(21ab, 14b) = 7b.
