Divisibility rule of 4: The divisibility rule of 4

The divisibility rule of 4 states that a number is divisible by 4 completely if its last two digits are zero or multiples of 4 . The divisibility rule of 4 remains same for all digit numbers. A divisibility rule is a method that helps check if a number is divisible by another number more quickly, without performing the full division. Example: Is 4725 divisible by 9? By direct division: 4725 ÷ 9 = 525, so yes, it is divisible. By applying the rule of 9: Add the digits → 4 + 7 + 2 + 5 = 18. Since 18 is divisible by 9, 4725 is also divisible by 9. Note: 0 is divisible by all the non-zero integers with no remainder. However, 0 cannot be divided by itself, since division by zero is ...
