Divisibility Rule of 481

The divisibility rule for 481 is a method by which we can determine if a number is divisible by 481 without using the division method. Let's check whether 1443 is divisible by 481 with the divisibility rule.
 

Step 1: Take the last digit of the number. Here, in 1443, 3 is the last digit.

Step 2: Multiply this last digit by 2 and subtract it from the remaining number formed by the other digits. So, 3×2=6 and 144-6=138.

Step 3: Repeat the process until you reach a number that is manageable. Since 138 is not a multiple of 481, we will continue the process (if necessary).

Step 4: If the result obtained is a multiple of 481, then the original number is divisible by 481. Otherwise, it is not. Since 138 is not a multiple of 481, 1443 is not divisible by 481.
 

Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 481.

• Know the multiples of 481: Memorize the multiples of 481 (481, 962, 1443, etc.) to quickly check the divisibility. If the result from the subtraction is a multiple of 481, then the number is divisible by 481.
   
• 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 manageable and check for divisibility.
   
• Use the division method to verify: Students can use the division method as a way to verify and cross-check their results. This will help them verify and also learn.
   

• Divisibility rule: The set of rules used to find out whether a number is divisible by another number or not. For example, a number is divisible by 481 if it follows the specific rule for 481.
   
• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 481 are 481, 962, 1443, etc.
   
• Integers: Integers are numbers that include all whole numbers, negative numbers, and zero.
   
• Subtraction: Subtraction is the process of finding the difference between two numbers by reducing one number from another.
   
• Verification: The process of using the division method to confirm the results obtained through the divisibility rule.
