What means divisibility test?
Definition of Divisibility Tests A divisibility test is an easy way of finding out whether a given integer is divisible by a fixed divisor without executing the division, usually by examining its digits. We say that a number is divisible by another number if the result of the division is a whole number”.
What is divisibility test with example?
Divisibility test for 6 A number is divisible by 6 if its last digit is an even number or zero and the sum of the digits is a multiple of 3. For example, 270 is divisible by 2 because the last digit is 0. The sum of the digits is: 2 + 7 + 0 = 9 which is also divisible by 3. Therefore, 270 is divisible by 6.
What is divisibility mean?
the capacity of being divided. Mathematics. the capacity of being evenly divided, without remainder.
What is divisibility test of 11?
Here an easy way to test for divisibility by 11. Take the alternating sum of the digits in the number, read from left to right. If that is divisible by 11, so is the original number. So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.
What does divisibility rule mean?
A divisibility rule is a shorthand and useful way of determining whether a given integer is divisible by a fixed divisor without performing the division, usually by examining its digits.
What is this word divisible?
capable of being evenly divided, without remainder.
What is the divisibility rule 9?
The divisibility rule of 9 states that if the sum of digits of any number is divisible by 9, then the number is also divisible by 9. It helps us in various concepts like finding divisors, HCF, LCM, measurements, and division.
What is the divisibility of 13?

|---|---|
| 24 | It is divisible by 3 and by 8. |
| 25 | Examine the number formed by the last two digits. |
| 26 | It is divisible by 2 and by 13. |
| Subtracting 5 times the last digit from 2 times the rest of the number gives a multiple of 26 |
How do you do a divisibility test?
The Divisibility Rules
- Any integer (not a fraction) is divisible by 1.
- The last digit is even (0,2,4,6,8)
- The sum of the digits is divisible by 3.
- The last 2 digits are divisible by 4.
- The last digit is 0 or 5.
- Is even and is divisible by 3 (it passes both the 2 rule and 3 rule above)
