Which of these numbers have 2 as a factor?
All even numbers greater than 0 have 2 as a factor.
Is 4 and 12 prime numbers?
4 and 12 are both even numbers greater than 2. They are composite numbers because 2 is a factor in addition to 1 and itself.
Are all multiples of 2 greater then 2 are composite numbers explain?
Yes, all multiples of 2 that are greater than 2 are composite numbers. In addition to 1 and the number itself, 2 is a factor of all even numbers.
Is the greatest common factor of two even numbers always even?
Assuming the second even number is equal to 4 or greater, than the highest common factor of the two numbers is equal to an even number 2 or greater. Why can't an odd factor be used? Any odd factor must be multiplied by (at least) 2 to create an even product (ie. the 1st even number). That same odd factor must be multiplied by (at least 2) and any other number to create a 2nd even product, thereby making the Greatest Common Factor (at least) 2 times the odd number....which is an even number.
Do all even numbers have 2 and a factor?
Actually they do because only even numbers have 2 as a factor.
Do all even whole numbers greater than 0 have two as a factor?
yea
Which of these numbers have 2 as a factor?
All even numbers greater than 0 have 2 as a factor.
Is two a factor of even odd or whole?
Two is a factor of all even numbers.
What numbers have 2 as a factor and are composite?
Any even number greater than two.
What are the even whole numbers greater than 21 but less than 28?
The even whole numbers greater than 21 and less than 28 are: 22, 24 and 26
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 the Greatest common factor of a pair of numbers even greater than both numbers?
No, the greatest common factor is never greater than the smallest number. The greatest common factor is the largest integer that divides evenly into all of the numbers listed.
Is two a factor of every even number?
in simple, whole numbers, yes.
How many even prime numbers are there and why?
There is only one even prime number, and that is 2. The reason is that all even numbers greater than 2 have 2 as a factor.
Which numbers less than 100 have even proper factors?
All even numbers greater than 2 have even proper factors, since they all have 2 as a proper factor.
Why are all prime numbers greater than 2 odd numbers?
Because all other even numbers have 2 as a factor.
Can two odd numbers have a greatest common factor that is an even number?
No. Because both numbers are even, they each have 2 as a factor. Even if they have a larger factor in common, it will be a multiple of 2, so the greatest common factor will be an even number.Yes. Two even numbers are each divisible by 2. The GCF must therefore always have two as one of its factors; this makes it even.
