Divisibility Rules

The number in the ones place is either 0, 2, 4, 6, or 8.

Every even integer is divisible by 2.

**2**

If the sum of the digits of a number is 3, 6, or 9, then the number is divisible by 3.

If the number formed by the tens and ones place is divisible by 4 then the entire number is divisible by 4.

If the number in the ones place is a 0 or a 5, then the number is divisible by 5.

If the number is divisible by both 2 and 3, then the number is divisible by 6.

Similar to the rule for 3; however the sum must be divisible by 9.

**3**

Ex.

Is 27 divisible by 3?

2+7=9, 9 is divisible by 3

27 is divisible by 3

**4**

**5**

**6**

**9**

Ex.

Is 35 divisible by 3?

3+5=8, 8 is not divisible by 3

35 is not divisible by 3.

Ex.

Is 7,485 divisible by 3?

7+4+8+5=24 if you do not know if 24 is divisible by 3 apply the rule again.

2+4=6, 6 is divisible by 3 so 24 is divisible by 3 and by extension so is 7,485.
