The concept of divisibility is essential in quantitative aptitude as it helps in simplifying calculations and solving problems efficiently. Understanding the divisibility rules of various numbers can significantly save time during exams, especially management entrance exams. In this study note, we will learn the divisibility rules of numbers 2, 3, 4, 5, 6, 7, 8, 9, 11, and 13, along with some examples.
A number is divisible by 2 if its unit digit is an even number (0, 2, 4, 6, or 8).
Example:
A number is divisible by 3 if the sum of its digits is divisible by 3.
Example:
A number is divisible by 4 if the number formed by its last two digits is divisible by 4.
Example:
A number is divisible by 5 if its unit digit is either 0 or 5.
Example:
A number is divisible by 6 if it is divisible by both 2 and 3.
Example:
A number is divisible by 7 if the difference between twice the unit digit and the number formed by the remaining digits is divisible by 7.
Example:
A number is divisible by 8 if the number formed by its last three digits is divisible by 8.
Example:
A number is divisible by 9 if the sum of its digits is divisible by 9.
Example:
A number is divisible by 11 if the difference between the sum of digits at odd places (1st, 3rd, 5th, etc.) and the sum of digits at even places (2nd, 4th, 6th, etc.) is either 0 or divisible by 11.
Example:
Here's the step-by-step procedure:
Example:
Check the divisibility of 507. Multiply the last digit (7) by 9 to get 63. Subtract 63 from the rest of the number (50), giving -13. -13 is a multiple of 13 (since -13 = -1*13), so 507 is divisible by 13.
