Rules of Divisibility

Rules of Divisibility

 
2: A number is divisible by 2 if the last digit (unit's digit) is even. e.g. 32, 459992

3: A number is divisible by 3, if the sum of digits of a number is divisible by 3.
    e.g. 252 = 2 + 5 + 2 = 9 ÷ 3 = 3 ∴ 252 is divisible by 3

4: A number is divisible by 4, if the last two digits of the number is divisible by 4.
    e.g. 81924 = since last two digits 24 is divisible by 4, hence the number.

5: A number is divisible by 5, if the last digit of the number is 0 or 5.
    e.g. 35, 200, 1005

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