The divisibility rules are the short-hand rules to identify if the given integers are divisible by the divisor.
List of divisibility rules
Examples:24, 380, 4502 are divisible by 2.
Examples: Consider the number 342. The sum of the digits is 3 + 4 + 2 = 9 Since the number 9 is divisible by 3. Therefore, 342 is also divisible by 3.
Examples:Consider the number 420.
The last two digits of the number is 20.
Since the number 20 is divisible by 4. Therefore, 420 is also divisible by 4.
Examples:25, 340, 765 are divisible by 5.
Examples:Consider the number 84.
The last digit is 4, 84 is divisible by 2.
The sum of the digit is 8 + 4 = 12. The number 12 is divisible by 3. Therefore, 84 is divisible by 3.
The number 84 is divisible by both 2 and 3. Therefore, 84 is also divisible by 6.
Examples:Consider the number 342.
The sum of the digits is 3 + 4 + 2 = 9
Since the number 9 is divisible by 9. Therefore, 342 is also divisible by 9.
Examples:240, 380, 450 are divisible by 10.
