Divisibility Rule of 751
The divisibility rule is a way to determine whether a number is divisible by another number without using the traditional 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 751.
What is the Divisibility Rule of 751?
The divisibility rule for 751 is a method by which we can determine if a number is divisible by 751 without using the division method.
Check whether 1502 is divisible by 751 with the divisibility rule.
Step 1: Separate the last three digits of the number. Here in 1502, the last three digits are 502.
Step 2: Subtract the last three digits from the remaining part of the number, which is 1 in this case. So, 1 - 502 = -501.
Step 3: If the result is a multiple of 751, then the number is divisible by 751. Since -501 is not a multiple of 751, 1502 is not divisible by 751.
Tips and Tricks for Divisibility Rule of 751
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 751.
Know the multiples of 751:
Memorize the multiples of 751 (751, 1502, 2253, etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 751, then the number is divisible by 751.
Use the absolute value:
If the result we get after the subtraction is negative, we will consider its absolute value for checking divisibility.
Repeat the process for large numbers:
Students should keep repeating the divisibility process until they reach a result that is clearly a multiple of 751.
Use the division method to verify:
Students can use the division method to verify and cross-check their results. This will help them to verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 751
The divisibility rule of 751 helps us quickly check if a given number is divisible by 751, but common mistakes like calculation errors can lead to incorrect results. Here we will understand some common mistakes and how to avoid them.
Mistake 1
Not following the correct steps.
Students should follow the correct steps: separate the last three digits, subtract them from the remaining part, and check if the result is a multiple of 751.
Mistake 2
Confusing the subtraction order.
Ensure that the last three digits are subtracted from the remaining part, not the other way around.
Mistake 3
Not repeating the process when the result is large.
Students should repeat the process if the result is not clearly a multiple of 751 after subtraction.
Mistake 4
Not considering the absolute value for negative results.
Use the absolute value of the result to check for divisibility.
Mistake 5
Confusing the steps.
Practice regularly to avoid confusion and remember the correct steps.
Divisibility Rule of 751 Examples
Problem 1
Is 1502 divisible by 751?
Yes, 1502 is divisible by 751.
Explanation
To check if 1502 is divisible by 751, perform the following:
1) Subtract the last three digits from twice the rest of the number, 1 × 2 = 2.
2) The remaining part of the number is 1, so 1 × 2 = 2.
3) Subtract 2 from 502, resulting in 500.
4) Since 500 is divisible by 751 (751 × 0 = 0), the original number 1502 is divisible by 751.
Problem 2
Determine if 3004 is divisible by 751.
No, 3004 is not divisible by 751.
Explanation
To verify divisibility by 751, follow these steps:
1) Divide the number into two parts: 3 and 004.
2) Multiply 3 by 2, resulting in 6.
3) Subtract 6 from 4, resulting in -2.
4) Since -2 is not divisible by 751, 3004 is not divisible by 751.
Problem 3
Is -1502 divisible by 751?
Yes, -1502 is divisible by 751.
Explanation
To check divisibility of -1502 by 751, ignore the negative sign and proceed:
1) Take the number 1502.
2) Multiply 1 (the number of hundreds) by 2, resulting in 2.
3) Subtract 2 from 502, resulting in 500.
4) Since 500 is divisible by 751 (751 × 0 = 0), -1502 is divisible by 751.
Problem 4
Can 2253 be divisible by 751 following the divisibility rule?
No, 2253 isn't divisible by 751.
Explanation
To check if 2253 is divisible by 751, use the divisibility rule:
1) Divide the number into 2 and 253.
2) Multiply 2 by 2, resulting in 4.
3) Subtract 4 from 253, resulting in 249.
4) Since 249 is not divisible by 751, 2253 is not divisible by 751.
Problem 5
Check the divisibility rule of 751 for 752.
No, 752 is not divisible by 751.
Explanation
To check the divisibility rule of 751 for 752, follow these steps:
1) Divide the number into 0 and 752.
2) Multiply 0 by 2, resulting in 0.
3) Subtract 0 from 752, resulting in 752.
4) Since 752 is not divisible by 751, 752 is not divisible by 751.
