Every even number is divisble by two. ALWAYS. That is why 2 is in every even factor.

2 is a factor of every even number. Adding or subtracting one from an even number leaves an odd number. Since even and odd numbers alternate, 2 will be a factor of every other number.

That's the definition of an even number. If they didn't have 2 as a factor, they wouldn't be even.

because 70 is an even number, and every even number has 2 as a factor.

Even numbers, by definition, are divisible by 2. That means that every even number has at least one 2 as a factor. If every even number has one, then any set of even numbers will have at least one 2 as a common factor. Since that number has two as a factor, it's even.

Every number to which 2 is a factor. Therefore, every multiple of two; hence, every even number.

It's easy to see whether 2 is a factor of a number because 2 is a factor of every even number and not a factor of any odd number.

By definition, every even number has 2 as a factor. That means that, at a minimum, every set of even numbers will have a common factor of 2. The GCF could be higher, of course, but that common factor of 2 will always be there, making the numbers even.

Yes.

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.

Think about it!

Any and every even number.

Because 2 can divide evenly into 44 with no remainder. Every even number has two as a factor.

Every even number but 2. Even numbers have 2 as a factor (by definition), so higher even numbers can be separated into two factors, 2 and some other number. For example, 6 = 2 x 3.

A number will have a factor of 2 if it is even.

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. Every even number has a factor of 2. So any two even numbers share 2 as a factor. So the greatest common factor has to be at least 2.

If 2 is a factor, the number is even.

2 cannot be a factor of an odd number, 2 must be a factor of an even number.

Having a factor of 2 defines an even number. Multiplying anything that has a factor of 2 by anything else will create a product that has a factor of 2, which will be by definition an even number.

Yes, it is. Any whole number times an even number will be even. This is because whole numbers can be represented as the product of their prime factors. Every even number contains 2 as a prime factor (thereby excluding all even numbers above 2 from being prime.) Additionally, the product of any two numbers is equal to the product of their prime factors. This means that the result of multiplying an even number by a whole number will always have a prime factor of 2, making it an even number.

Yes, because 2 is a factor of 4.

Because every even number greater than 2 has two as a factor.

Every number that includes a factor of 2 is an even number. Every number that ends in a 5 is an odd number.

Can be divided by itself
