Is 2 a factor of 49?
In order to determine if 2 is a factor of 49 (or any other number), ask yourself if the number is even or odd. If the number is odd, it is not a factor of 2. 49 is odd, so 2 is not a factor of 49. You can also divide 2 into the number. If there is no remainder, 2 is a factor of the number. 49 divided by 2 is 24 with a remainder of 1, so 2 is not a factor of 49.
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.
Are multiples of 8 also multiples of 4?
