Divisibility Rule of 763
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 763.
What is the Divisibility Rule of 763?
The divisibility rule for 763 is a method by which we can find out if a number is divisible by 763 or not without using the division method. Let's check whether 1526 is divisible by 763 using the divisibility rule.
Step 1: Multiply the last digit of the number by 2, here in 1526, 6 is the last digit. Multiply it by 2. 6 × 2 = 12.
Step 2: Subtract the result from Step 1 from the remaining values but do not include the last digit. i.e., 152 - 12 = 140.
Step 3: As it is shown that 140 is a multiple of 763, therefore, the number is divisible by 763. If the result from step 2 isn't a multiple of 763, then the number isn't divisible by 763.
Tips and Tricks for Divisibility Rule of 763
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 763.
- Know the multiples of 763: Memorize the multiples of 763 (763, 1526, 2289, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 763, then the number is divisible by 763.
- 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 763.
For example: Check if 22890 is divisible by 763 using the divisibility test.
Multiply the last digit by 2, i.e., 0 × 2 = 0.
Subtract the remaining digits excluding the last digit from 0, 2289 - 0 = 2289.
Still, 2289 is a large number, hence we will repeat the process again and multiply the last digit by 2, 9 × 2 = 18.
Now subtract 18 from the remaining numbers excluding the last digit, 228 - 18 = 210.
As 210 is not a multiple of 763, 22890 is not divisible by 763.
- 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.
Common Mistakes and How to Avoid Them in Divisibility Rule of 763
The divisibility rule of 763 helps us to quickly check if the given number is divisible by 763, but common mistakes like calculation errors lead to incorrect conclusions. Here we will understand some common mistakes that will help you to understand.
Mistake 1
Not following the correct steps.
Students should follow the correct steps that involve multiplying the last digit by 2 and then subtracting the result from the remaining digits excluding the last digit and checking whether it is a multiple of 763.
