Divisibility Rule of 557
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 557.
What is the Divisibility Rule of 557?
The divisibility rule for 557 is a method by which we can find out if a number is divisible by 557 or not without using the division method. Check whether 1114 is divisible by 557 with the divisibility rule.
Step 1: Multiply the last three digits of the number by 2, here in 1114, 114 are the last three digits, multiply it by 2. 114 × 2 = 228.
Step 2: Subtract the result from Step 1 with the remaining values but do not include the last three digits. i.e., 1–228 = -227.
Step 3: As it is shown that -227 is not a multiple of 557, therefore, the number is not divisible by 557. If the result from step 2 is a multiple of 557, then the number is divisible by 557.
Tips and Tricks for Divisibility Rule of 557
Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 557.
- Know the multiples of 557: Memorize the multiples of 557 (557, 1114, 1671, 2228, 2785…etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 557, then the number is divisible by 557.
- Use the 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 557.
For example: Check if 2785 is divisible by 557 using the divisibility test. Multiply the last three digits by 2, i.e., 785 × 2 = 1570.
Subtract the remaining digits excluding the last three digits by 1570, 2–1570 = -1568. Still, -1568 is a large number, hence we will repeat the process again and multiply the last three digits by 2, 568 × 2 = 1136.
Now subtracting 1136 from the remaining numbers excluding the last three digits, 1–1136 = -1135. Since -1135 is not a multiple of 557, 2785 is not divisible by 557.
- 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 557
The divisibility rule of 557 helps us to quickly check if the given number is divisible by 557, but common mistakes like calculation errors lead to incorrect calculations. 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 are multiplying the last three digits with 2 and then subtracting the result from the remaining digits excluding the last three digits and checking whether it is a multiple of 557.
Divisibility Rule of 557 Examples
Problem 1
Is 1671 divisible by 557?
Yes, 1671 is divisible by 557.
Explanation
Let's verify using a hypothetical divisibility rule for 557.
1) Consider the last three digits as a separate number, which is 671.
2) Check if 671 equals 0 or is a multiple of 557. In this case, 671 is not 0, but if we perform the division, 1671 ÷ 557 = 3, with no remainder.
Therefore, 1671 is divisible by 557.
Problem 2
Check the divisibility rule of 557 for 2785.
No, 2785 is not divisible by 557.
Explanation
Using a conjectural divisibility rule for 557:
1) Consider the last three digits as a separate number, which is 785.
2) Check if 785 equals 0 or is a multiple of 557. Here, 785 is not 0, and 785 ÷ 557 leaves a remainder.
Hence, 2785 is not divisible by 557.
Problem 3
Is 0 divisible by 557?
Yes, 0 is divisible by 557.
Explanation
Any number, including 0, is divisible by any non-zero integer.
Therefore, 0 ÷ 557 = 0 with no remainder, so 0 is divisible by 557.
Problem 4
Can 1114 be divisible by 557 following the divisibility rule?
No, 1114 is not divisible by 557.
Explanation
To check if 1114 is divisible by 557:
1) Consider the last three digits as a separate number, which is 114.
2) Check if 114 equals 0 or is a multiple of 557. Here, 114 is not 0, and 114 ÷ 557 results in a non-zero remainder.
Thus, 1114 is not divisible by 557.
Problem 5
Check the divisibility rule of 557 for 3342.
Yes, 3342 is divisible by 557.
Explanation
Using a hypothetical rule for divisibility by 557:
1) Consider the last three digits as a separate number, which is 342.
2) Check if 342 equals 0 or is a multiple of 557. For this scenario, 3342 ÷ 557 = 6, with no remainder.
Therefore, 3342 is divisible by 557.
