Divisibility Rule of 988
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 divisibility rules for quick math, dividing things evenly, and sorting items. In this topic, we will learn about the divisibility rule of 988.
What is the Divisibility Rule of 988?
The divisibility rule for 988 is a method by which we can determine if a number is divisible by 988 without performing the division method. Check whether 1976 is divisible by 988 with the divisibility rule.
Step 1: Divide the number into groups of three digits starting from the right. Here in 1976, it becomes 1,976.
Step 2: Consider only the last group of three digits for now, i.e., 976. Subtract it from the number formed by the remaining groups. Here, 1 - 976 = -975.
Step 3: Check if the result is a multiple of 988. If it is, the original number is divisible by 988. Since -975 is not a multiple of 988, 1976 is not divisible by 988.
Tips and Tricks for Divisibility Rule of 988
Learn the divisibility rule to help master division. Let’s explore a few tips and tricks for the divisibility rule of 988.
Know the multiples of 988:
Memorize the first few multiples of 988 (988, 1976, 2964, 3952, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 988, then the number is divisible by 988.
Use absolute values:
If the subtraction result is negative, consider its absolute value for checking divisibility.
Repeat the process for large numbers:
Continue applying the divisibility process until reaching a smaller number that can easily be checked for divisibility by 988.
Use the division method to verify:
You can use the division method to verify and crosscheck results, reinforcing understanding.
Common Mistakes and How to Avoid Them in Divisibility Rule of 988
The divisibility rule of 988 helps us quickly check if a given number is divisible by 988, but common mistakes like calculation errors can lead to incorrect conclusions. Here are some common pitfalls and solutions:
Mistake 1
Not following the correct steps.
Follow the correct steps by grouping digits, subtracting properly, and checking for multiples of 988
Mistake 2
Including non-three-digit groups in subtraction.
Ensure only the last group of three digits is subtracted from the remaining number.
Mistake 3
Not repeating the process for large results.
Continue the process until reaching a manageable number.
Mistake 4
Ignoring negative values.
Consider negative results as positive for checking divisibility.
Mistake 5
Confusing or forgetting steps.
Practice regularly to remember and correctly apply the steps.
