Divisibility Rule of 288

The divisibility rule for 288 is a method by which we can find out if a number is divisible by 288 or not without using the division method. Check whether 5184 is divisible by 288 with the divisibility rule.

Step 1: Check if the number is divisible by 2. Since 5184 ends in 4, it is divisible by 2.

Step 2: Check if the number is divisible by 9. Sum the digits of 5184: 5+1+8+4=18. Since 18 is divisible by 9, 5184 is divisible by 9.

Step 3: Check if the number is divisible by 16. Take the last four digits (since 288 is (16 times 18)), which are 5184, and see if they are divisible by 16. 5184 divided by 16 equals 324, so 5184 is divisible by 16.

Since 5184 is divisible by 2, 9, and 16, it is divisible by 288.

Learning the divisibility rule helps kids master division. Let’s learn a few tips and tricks for the divisibility rule of 288:

Know the multiples of 288:

Memorize the multiples of 288 (288, 576, 864, etc.) to quickly check divisibility. If a number is divisible by these, it is divisible by 288.

Use the divisibility rules of 2, 9, and 16:

If a number is divisible by these three numbers, it is divisible by 288.

Repeat the process for large numbers:

Students should keep repeating the divisibility process on large numbers until they reach a small number that is divisible by 288.

Use the division method to verify:

Students can use the division method to verify and crosscheck their results. This will help them ensure accuracy and understanding.
