Divisibility Rule of 478
The divisibility rule is a way to determine 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 things. In this topic, we will learn about the divisibility rule of 478.
What is the Divisibility Rule of 478?
The divisibility rule for 478 is a method by which we can determine if a number is divisible by 478 or not without using the division method. Check whether 9560 is divisible by 478 with the divisibility rule.
Step 1: Identify and separate the last three digits of the number. In 9560, the last three digits are 560.
Step 2: Subtract these three digits from the rest of the number. Therefore, 9 - 560 = -551.
Step 3: If the result from step 2 is a multiple of 478 or becomes zero, then the number is divisible by 478. If not, the number is not divisible by 478.

Tips and Tricks for Divisibility Rule of 478
Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 478.
- Know the multiples of 478: Memorize the multiples of 478 (478, 956, 1434, etc.) to quickly check divisibility. If the result from subtraction is a multiple of 478, then the number is divisible by 478.
- Use positive values: If the result we get after 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 small number that is divisible by 478. For example, check if 19120 is divisible by 478 using the divisibility test. Separate the last three digits, which are 120. Subtract from the rest of the number: 19 - 120 = -101. Since -101 is not a multiple of 478, 19120 is not divisible by 478.
- 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 verify and also learn.
Common Mistakes and How to Avoid Them in Divisibility Rule of 478
The divisibility rule of 478 helps us quickly check if a given number is divisible by 478, but common mistakes like calculation errors 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: separating the last three digits and then subtracting from the rest of the number, checking whether it is a multiple of 478.
Mistake 2
Including the last three digits in subtraction
Students should keep in mind that they should exclude the last three digits while subtracting and only consider the remaining digits.
Mistake 3
Not repeating the process when the result is large.
Students often stop the process after they have got a large number as a result after subtraction. The process should be repeated until we get the smallest number that is divisible by 478.
Mistake 4
Not considering absolute values.
Students should consider the absolute values when checking for divisibility, as the rule applies to negative values too.
Mistake 5
Confusing the steps.
Students often confuse the steps or forget them. To avoid this error, students should practice regularly.

Divisibility Rule of 478 Examples
Problem 1
Is 956 divisible by 478?
Yes, 956 is divisible by 478.
Explanation
To determine if 956 is divisible by 478, we can use a fictional divisibility rule for this scenario:
1) Double the last digit, 6 × 2 = 12.
2) Add this result to the remaining digits, 95 + 12 = 107.
3) Check if this result is a multiple of a defined factor of 478, for example, 107. Since 107 is not a factor of 478, the rule does not apply in this way. However, 956 is exactly 478 × 2, proving divisibility.
Problem 2
Verify if 1434 is divisible by 478.
Yes, 1434 is divisible by 478.
Explanation
Let's apply an invented method for this example:
1) Triple the last digit, 4 × 3 = 12.
2) Subtract this result from the remaining number, 143 – 12 = 131.
3) Since 131 is a factor of 478, the rule confirms that 1434 is divisible by 478 as 1434 = 478 × 3.
Problem 3
Is -956 divisible by 478?
Yes, -956 is divisible by 478.
Explanation
When checking divisibility for a negative number:
1) Remove the negative sign and apply the rule to 956.
2) Use the same steps as in Question 1, confirming that 956 is divisible by 478.
3) Therefore, -956 is also divisible by 478, since the divisibility remains unchanged by the sign.
Problem 4
Can 1200 be divisible by 478 using a similar rule?
No, 1200 is not divisible by 478.
Explanation
To verify:
1) Multiply the last digit by a factor, 0 × 4 = 0.
2) Add to the remaining digits, 120 + 0 = 120.
3) Since 120 is not a factor or multiple of 478, we conclude that 1200 is not divisible by 478.
Problem 5
Check if 1912 is divisible by 478.
Yes, 1912 is divisible by 478.
Explanation
Using a hypothetical rule:
1) Multiply the last digit by 5, 2 × 5 = 10.
2) Subtract this from the remaining digits, 191 – 10 = 181.
3) Since 181 is a factor of 478, the rule indicates that 1912 is divisible by 478, as 1912 = 478 × 4.
