If the last two digits of a number are divisible by 4, the whole number is divisible by 4. If the sum total of the digits in a number are a multiple of 9, the whole number is a multiple of 9.
If the number is even, it's divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3. If the last two digits are a multiple of 4, the whole number is divisible by 4. If the last digit is a 0 or a 5, the whole number is divisible by 5. If the number is even and divisible by 3, it's divisible by 6. If the sum of the digits is a multiple of 9, the whole number is divisible by 9. If the number ends in 0, it's divisible by 10.
A number that is divisible by 2, 3, 4, 5, 6, 8, 9, and 10 must be divisible by the least common multiple (LCM) of these numbers. The LCM of 2, 3, 4, 5, 6, 8, 9, and 10 is 360. Therefore, any multiple of 360 will be divisible by all of these numbers.
To find a number that is not a common multiple of 4 and 9, we need to consider the multiples of each number. The multiples of 4 are 4, 8, 12, 16, 20, 24, ... and the multiples of 9 are 9, 18, 27, 36, 45, ... The first number in the list of multiples of 4 that is not a multiple of 9 is 4. Therefore, 4 is a number that is not a common multiple of 4 and 9.
