Question

The GCF of an odd number and an even number is always even.

Answer 1

This statement is not true.

The opposite is true: the gcf of an odd number and an even number is always odd.

All the factors of an odd number are odd; or to put it another way: If a number has an even factor, the number itself must be even.

Thus the only common factors between odd and even numbers must be odd.

Answer 2

solution:

It is Never even. Because no even number can be a factor of the odd number.
