If n3 is even then n is even?
Can't quite tell what you mean by n3. 1) If that's n3, then: If n3 is even, it can be expressed as n * n * n = 2 * t (t is a natural number). You can see that two is a factor of n3, and so it has to be a factor of n, because there is no ther number that could contribute to it. So n is even too. 2) If you mean 3 * n, then: 3 * n = 2 * t, where t is a natural number. Again, the only number to contribute factor 2 for the right side of equation is n. So n has to be even too.
Are odd numbers divisible by even numbers?
No. because odd numbers don't have 2 as a factor but even numbers do. So it won't be a whole number.
Is 2 an even or odd number?
2 is an even number. I believe your confusion comes from the fact that 2 is a prime number, but it is still even. It is the only even number that is prime.
If the gcf of an odd number and an even number is 33 and the greater number is 99 what is the other number?
For a greatest common factor of 33, the number 66 (2 x 33) would be a smaller multiple than 99 (3 x 33).
Is 256 a prime or composite number?
256 is not prime. 256 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2
Why is 2 in every even factor?
Every even number is divisble by two. ALWAYS. That is why 2 is in every even factor.
Why is 2 a factor of every other number?
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.
Why does every even number have 2 as a factor?
That's the definition of an even number. If they didn't have 2 as a factor, they wouldn't be even.
Why is 2 a prime factor of 70?
because 70 is an even number, and every even number has 2 as a factor.
Is 2 a factor of every even number?
Yes.
Which number is divisible by 2?
Every number to which 2 is a factor. Therefore, every multiple of two; hence, every even number.
Is 2 a factor of every even natural number?
Think about it!
What is the multiplication that has 2 as a factor?
Any and every even number.
Why is 2 a easy factor?
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.
Why is the greatest common factor of two even numbers always even?
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.
Why is the gcf of any even number always even?
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.
Why is the statement is the greatest common factor of even numbers is always even true?
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.
