Divisibility is a method for calculating the number of times a given number, generally referred as the “Divisor” is enclosed in a different given digit known as the “Dividend.” The number, usually is referred as the “Quotient.” The leftover of dividend from the divisor is known as the “Remainder.” In this Page Divisibility Questions and Answers is given for Practices.

The formula for checking divisibility of a given number is Dividend = (Divisor x Quotient) + Remainder.

Rules for Divisibility

Rule for 2 A number is divisible by 2 when the number ends with 0,2,4,6,8.

Rule for 3 If the sum of digit is divisible by 3 than the number is divisible by 3.

Rule for 4 If the last two digit is divisible by 4, than the number is divisible by 4.

Rule for 5 Number is divisible by 5 if the last digit is 0 or 5.

Rule for 6 A number is divisible by if number is divisible by 2 and 3.

Rule for 7 : Double the last digit and subtract it from the remaining leading truncated number to check if the result is divisible by 7 until no further division is possible

Rule for 8 If the last 3 number is divisible by 8 than the number is divisible by 8.

Rule for 9 Same as divisibility of 3 but sum of digits is divide by 9 in place of 3

Rule for 10 If the last digit is 0 than the number is divisible by 10.

Rule for 25

Any value whose last two numbers are either 0 or are the multiples of 25 is absolutely divisible by 25.
