DIVISIBILITY RULES The following rules will help you determine if a number is divisible by another number. Divisible means to divide into evenly.
A number is divisible by 2 if:it is an even number. An even number ends with 0,2,4,6,8. Example: 496- ends with an even number. 496 is divisible by 2.
A number is divisible by 5 if:the ones digit is 0 or 5. Example #1: 680 – ends with a 0 680 is divisible by 5. Example #2: 965 – ends with a 5 965 is divisible by 5.
A number is divisible by 10 if:the ones digit is a 0. Example: 950 – ends with a 0 950 is divisible by 10.
A number is divisible by 3 if:the sum of the digits is divisible by 3. Example: 861: = 15 and 15 3 = 5 861 is divisible by 3
A number is divisible by 9 if:the sum of the digits is divisible by 9. Example: 837: = 18 and 18 9 = 2 837 is divisible by 9
A number is divisible by 6 if:it is even AND it is divisible by 3. Example: it is even AND = 18 and 18 3 = 6 864 – is divisible by 6
Rules of Divisibility. Divisible by 2? If the last digit is even then the number is divisible by 2. Even digits are 0, 2, 4, 6 and 8 (yes zero is even!)
