Divisibility Questions and Answers
Definition of Divisibility
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.”
Formula or Rule
The formula for DivisibilityThe formula for checking divisibility of a given number is Dividend = (Divisor + Quotient) + Remainder.
- A given digit whose units place has 0 or any other digit which can be divided by 2.
- A given digit can be divisible by 4 if the preceding two numbers are either 0 or are divisible by 4.
- Any digit that ends with a 5 or 0 is perfectly divisible by 5
- For identifying any digit that is divisible by 7, one is required primarily to double the last number of the given value.
- Any number whose last three digits are either 0 or are perfectly divisible by 8 can be divided by 8.
- When the difference in the total of the numbers at odd places as well as the sum of the numbers at even places of any value is 0 or a multiple of 11, that value or digit is absolutely divisible by 11
- Any value whose last two numbers are either 0 or are the multiples of 25 is absolutely divisible by 25.
