Divisibility Rule of 989
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 989.
What is the Divisibility Rule of 989?
The divisibility rule for 989 is a method by which we can determine if a number is divisible by 989 without using the division method. Check whether 1978 is divisible by 989 with the divisibility rule.
Step 1: Separate the last three digits of the number, here in 1978, 978 is the last three digits.
Step 2: Subtract the number formed by the last three digits from the number formed by the remaining digits, i.e., 1 - 978 = -977.
Step 3: As it is shown that the difference is not zero, therefore, the number is not divisible by 989. If the result f
Tips and Tricks for Divisibility Rule of 989
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 989.
Know the multiples of 989:
Memorize the multiples of 989 (989, 1978, 2967, 3956, etc.) to quickly check divisibility. If the result from the subtraction is zero, then the number is divisible by 989.
Use absolute values:
If the result we get after subtraction is negative, consider its absolute value for checking divisibility.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a small number that is zero after subtraction. For example, check if 2967 is divisible by 989 using the divisibility test. Separate the last three digits, i.e., 967. Subtract 967 from the remaining number, 2 - 967 = -965. Since the subtraction result is not zero, 2967 is not divisible by 989.
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.
