## What is the rule for making a number divisible by 3?

Rule: A number is divisible by 3 if the sum of its digits is divisible by 3. 375, for instance, is divisible by 3 since sum of its digits (3+7+5) is 15. And 15 is divisible by 3.

### How to check if a number is evenly divisible by 3?

Check if the following number: is evenly divisible by three. 1 + 4 = 5 and since 5 is not divisible by 3, so 14 is also not. 1 + 2 + 4 = 7 which is no good, since 7 is not evenly divisible by 3. 1 + 0 + 0 + 0 + 2 + 0 + 0 + 1 = 4 so this very large also does not pass this divisibility test. What is the divisibility by 4 rule?

### Is the last digit of a number divisible by 2?

Since the last digit is a 2, the entire number, 12, is an even number and therefore divisible by 2. Since the last digit is an 8, this is an an even number and therefore divisible by 2. Since the last digit is 0, this is an an even number and therefore divisible by 2.
