The gcf of two even number is 2. never true always or sometimes

In this question we have to check whether the statement " The gcf of two even number is 2" is never true or sometimes true.

We will take two examples.

Lets take two numbers 4 and 6. They both are even and there GCF is 2. So the statement given is true.

Let's take 4 and 8. Both are even and the GCF is 4 which is not 2. SO the statement is not true.

So the given statement is sometimes true.
