- Numbers are divisible by 2 if the ones digit is evenly divisible by 2. This means that even numbers are divisible by 2.
- Numbers are divisible by 3 if the sum of all the individual digits is evenly divisible by 3. For example, the sum of the digits for the number 3627 is 18, which is evenly divisible by 3 so the number 3627 is evenly divisible by 3.
- Whole numbers are divisible by 4 if the number formed by the last two individual digits is evenly divisible by 4. For example, the number formed by the last two digits of the number 3628 is 28, which is evenly divisible by 4 so the number 3628 is evenly divisible by 4.
- Numbers are evenly divisible by 5 if the last digit of the number is 0 or 5.
