An odd factor is a number that cannot be divided by 2. if it can be divided by 2 it is an even factor or even number.

no
It is NEVER even. Because no even number can be a factor of the odd number.
No, always odd.
2 cannot be a factor of an odd number, 2 must be a factor of an even number.
Yes. The odd number does not have 2 as a factor (or else the number would be even). So the gcf does not have 2 as a factor. So the gcf must be odd.
The GCF of an odd and an even number must be odd since odd numbers do not have any even factors.
No, always odd.
It CAN'T be even, since the number 2 is not a factor of the odd number. "Even" means that a number is a multiple of 2.
No, always odd.
