Divisibility Rule of 961
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 961.
What is the Divisibility Rule of 961?
The divisibility rule for 961 is a method by which we can find out if a number is divisible by 961 or not without using the division method. Check whether a number is divisible by 961 by using the divisibility rule.
Step 1: Take the last digit of the number and multiply it by 100.
Step 2: Subtract the result from Step 1 from the rest of the number, excluding the last digit.
Step 3: If the result is a multiple of 961, the original number is divisible by 961. If it isn't a multiple of 961, then the number isn't divisible by 961.
Let's check whether 1922 is divisible by 961 using the divisibility rule:
Step 1: Multiply the last digit by 100. Here, 2 × 100 = 200.
Step 2: Subtract 200 from the remaining number, excluding the last digit: 192 - 200 = -8.
Step 3: Since -8 is not a multiple of 961, 1922 is not divisible by 961.
Tips and Tricks for Divisibility Rule of 961
Learning the divisibility rule can help individuals master division. Let’s learn a few tips and tricks for the divisibility rule of 961.
Know the multiples of 961:
Memorize the multiples of 961 (961, 1922, 2883, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 961, then the number is divisible by 961.
Use negative numbers:
If the result we get after the subtraction is negative, consider it as positive for checking the divisibility of a number.
Repeat the process for large numbers:
Continue the divisibility process until reaching a small number that is divisible by 961. For example, if checking a larger number, continue the process iteratively.
Use the division method to verify:
Use the division method to verify and cross-check results. This helps confirm and reinforce learning.
