By definition, every even number has 2 as a factor. That means that every set of even numbers will have at least 2 as a common factor. The GCF might be higher, but if it has 2 as a factor, it's even.
No not always as for example the GCF of 7 and 21 is 7
There's a lot of possibilities. Any set of consecutive even numbers has a GCF of 2.
The GCF is 2.
No, the GCF of any two numbers may be odd or even. For instance:The GCF of 2 and 4 is 2The GCF of 3 and 6 is 3The GCF of 14 and 21 is 7.
The GCF is 2.
Any consecutive even numbers have a GCF of 2.
2 and any even number, and many more
2 and any other even number.
True. Even numbers are even because they are multiples of 2. That means that any two even numbers will have at least 2 as a common factor. Since that number (the GCF) will have 2 as a factor, it will be a multiple of 2: an even number.
2The GCF of 2 and any even number is 2.
By definition, every even number has 2 as a factor. That means that every set of even numbers will have at least 2 as a common factor. The GCF might be higher, but if it has 2 as a factor, it's even.
The GCF is 1.
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.
No not always as for example the GCF of 7 and 21 is 7
If x is an odd number that is a common factor of 2 even numbers, so is 2x. So the answer is yes.
That can never be an even number.
