Divisibility Rule of 88

The divisibility rule for 88 is a method by which we can find out if a number is divisible by 88 or not without using the division method. Check whether 1232 is divisible by 88 with the divisibility rule.

Step 1: Check if the number is divisible by 8. For 1232, the last three digits are 232. Since 232 divided by 8 equals 29 with no remainder, it is divisible by 8.

Step 2: Check if the number is divisible by 11. To do this, take the alternating sum of the digits: (1 - 2 + 3 - 2 = 0). Since 0 is a multiple of 11, the number is divisible by 11.

Step 3: Since the number is divisible by both 8 and 11, it is divisible by 88.

Understanding the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 88.

• Know the multiples of 88: Memorize the multiples of 88 (88, 176, 264, 352, 440…etc.) to quickly check divisibility. If a number is a multiple of 88, it is divisible by 88.
   
• Check divisibility by 8 and 11: A number is divisible by 88 if it is divisible by both 8 and 11. Ensure you check for both conditions.
   
• Use the division method to verify: Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn.

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not.
   
• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 88 are 88, 176, 264, 352, etc.
   
• Integers: Integers are numbers that include all the whole numbers, negative numbers, and zero.
   
• Alternating sum: A method used in the divisibility rule of 11 where digits are alternately added and subtracted.
   
• Verification: The process of confirming the accuracy of a calculation or result, such as using division to check divisibility
