Divisibility Rule of 89

Professor Greenline Explaining Math Concepts

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 89.

What is the Divisibility Rule of 89?

The divisibility rule for 89 is a method by which we can determine if a number is divisible by 89 without using the division method. Check whether 2673 is divisible by 89 with the divisibility rule.
 

Step 1: Multiply the last digit of the number by 9. Here in 2673, 3 is the last digit, so multiply it by 9. 3 × 9 = 27.
 

Step 2: Subtract the result from Step 1 from the remaining values, excluding the last digit. i.e., 267–27 = 240.
 

Step 3: Repeat the process for the result from Step 2. Multiply the last digit (0) by 9. 0 × 9 = 0. Subtract from the remaining number: 24–0 = 24.
 

Step 4: Since 24 is not a multiple of 89, 2673 is not divisible by 89. If the result from the repeated process is a multiple of 89, then the number is divisible by 89.divisibility rule of 89

Tips and Tricks for Divisibility Rule of 89

Learning the divisibility rule helps kids master division. Let’s learn a few tips and tricks for the divisibility rule of 89.
 

  • Know the multiples of 89: Memorize the multiples of 89 (89, 178, 267, 356, 445, etc.) to quickly check divisibility. If the result from subtraction is a multiple of 89, then the number is divisible by 89.
     
  • Use negative numbers: If the result we get after the subtraction is negative, we will avoid the symbol and consider it as positive for checking the divisibility of a number.
     
  • Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is divisible by 89.

    For example, check if 7125 is divisible by 89 using the divisibility test. Multiply the last digit by 9, i.e., 5 × 9 = 45. Subtract from the remaining digits excluding the last digit: 712–45 = 667.

    Repeat the process: multiply the last digit (7) by 9, 7 × 9 = 63. Subtract from the remaining number: 66–63 = 3. Since 3 is not a multiple of 89, 7125 is not divisible by 89.
     
  • 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.
