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 .

a² + b²= c²

24² + 7² = c²

c= 25
