## Rules of Divisibility

A number is considered to be divisible by a given number if there is no remainder when the two numbers are divided. When working with large numbers, it is often easier to use divisibility tests instead of performing long division by hand.

**2: A number is divisible by 2 if the last digit is even (0, 2, 4, 6, or 8). **

For example, 48 is divisible by 2 because the last digit of 48 (8) is even.

**3: A number is divisible by 3 if the sum of the digits is divisible by 3. **

For example, 96 is divisible by 3 because 15 (9 + 6) is divisible by 3.

**4: A number is divisible by 4 if the last two digits are divisible by 4. **

For example, 124 is divisible by 4 because 24 (the last two digits) is divisible by 4.

**5: A number is divisible by 5 if the last digit is 0 or 5. **

For example, 1000 is divisible by 5 because the last digit is 0.

**6: A number is divisible by 6 if the number is divisible by both 2 and 3. **

For example, 72 is divisible by 6 because it is divisible by both 2 and 3. We know 72 is divisible by 2 because its last digit is an even number. We know 72 is divisible by 3 because 9 (7 + 2) is divisible by 3.

**8: A number is divisible by 8 if the last three digits are divisible by 8. **

For example, 160 is divisible by 8 because the last three digits (160) are divisible by 8 (8*20 = 160).

**9: A number is divisible by 9 if the sum of the digits is divisible by 9. **

For example, 333 is divisible by nine because 9 (3 + 3 + 3) is divisible by 9.

**10: A number is divisible by 10 if the last digit is 0. **

For example, 90 is divisible by 10 because the last digit is 0.
