Best Answer

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.
