It's very easy to test a number to see if it is divisible by 4 or by 9. If it passes both tests, then it is divisible by 4x9=36.
- To test for divisibility by 9, add the digits of the number. If the sum is divisible by 9, then the number is divisible by 9.
- To test for divisibility by 4, look at the last two digits. If they are a multiple of 4, then the number is divisible by 4.
