The Rule for10: Numbers that are divisible by 10 need to be even and divisible by 5, because the prime factors of 10 are 5 and 2. Basically, this means that for a number to be divisible by 10, the last digit must be a 0. Example:23,890 Take a look at the last digit: 23,890...
The Rule for 9: The prime factors of 9 are 3 and 3. So we can use a very similar rule to determine if a number is divisible by 9. Basically, we will see if the sum of the digits is divisible by 9. If it is, then the actual number is also divisible by 9. This is done the...

Let's look at some examples of k, how each k is factorized into prime-power pairs, and how that determines the divisibility rule for k: A number is divisible by 6 = 2 × 3 if and only if it is divisible by 2 and by 3. A number is divisible by 12 = 2² × 3 if and only...
