Is 3 a factor of 56902?

Well, isn't that a happy little question! Let's take a look. If a number is divisible by 3, the sum of its digits will also be divisible by 3. So, if we add up the digits of 56902 (5+6+9+0+2), we get 22, which is not divisible by 3. Therefore, 3 is not a factor of 56902. But that's okay, every number is special in its own way!
