3 Divisibility Rules 2 divides into all even numbers. 3 divides into a number if the sum of the digits of that number is divisible by 3.5 divides into numbers that end with a 5 or 0.9 divides into a number if the sum of the digits of that number is divisible by 9.10 divides into numbers that end with 0.
4 Example: Test each number for divisibility by 3. 216= 99 is divisible by 3, so 216 is divisible by 3.yes437= 1414 is not divisible by 3, so 437 is not divisible by 3.no
5 Example: Test the number for divisibility by 2, 5, or 10. 454,3202 works because the number is even.5 works because the number ends with 0.10 works because the number ends with 0.= 18.Is the number divisible by 9?18 is divisible by 9, so 454,320 is also divisible by 9.
