Continue ReadingUsing divisibility rules can help someone quickly find the factors of a number. All of the even numbers are always divisible by 2. If the digits that make up a number can be added to make a number that can be evenly divided by 3, the number itself is divisible by 3. All numbers that end in a 0 or a 5 are always divisible by 5.
