The divisibility rule is a way to find out whether a number is divisible by another number without using the division method. In real life, we can use the divisibility rule for quick math, dividing things evenly, and sorting things. In this topic, we will learn about the divisibility rule of 975.

What is the Divisibility Rule of 975?

The divisibility rule for 975 is a method by which we can determine if a number is divisible by 975 without using the division method. To apply this rule, a number must be divisible by 3, 5, and 13 (since 975 = 3 × 5 × 13).

Example: Check whether 2925 is divisible by 975.


Step 1: Check divisibility by 3. A number is divisible by 3 if the sum of its digits is divisible by 3. For 2925: 2 + 9 + 2 + 5 = 18, which is divisible by 3.


Step 2: Check divisibility by 5. A number is divisible by 5 if it ends in 0 or 5. 2925 ends in 5, so it is divisible by 5.


Step 3: Check divisibility by 13. A number is divisible by 13 if you can subtract 9 times the last digit from the rest of the number and get a result divisible by 13. For 2925: Subtract 9 times 5 (last digit) from 292: 292 - 45 = 247, and 247 is divisible by 13.


Since 2925 is divisible by 3, 5, and 13, it is divisible by 975.
