Divisibility Rule of 141

The divisibility rule for 141 is a method by which we can find out if a number is divisible by 141 or not without using the division method. Check whether 8463 is divisible by 141 with the divisibility rule.
 

Step 1: Multiply the last two digits of the number by 2, here in 8463, 63 is the last two digits. Multiply them by 2: 63 × 2 = 126.
 

Step 2: Subtract the result from Step 1 from the remaining values but do not include the last two digits. i.e., 84 – 126 = -42.
 

Step 3: As it is shown that -42 is not a multiple of 141, therefore, the number is not divisible by 141.
 

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 141.
 

• Know the multiples of 141: Memorize the multiples of 141 (141, 282, 423, 564, 705…etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 141, then the number is divisible by 141.
   
• Use the negative numbers: If the result we get after subtraction is negative, we will ignore 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 141. 
  
  For example: Check if 12807 is divisible by 141 using the divisibility test. Multiply the last two digits by 2, i.e., 07 × 2 = 14. Subtract the remaining digits excluding the last two digits by 14, 128 – 14 = 114. Still, 114 is not a multiple of 141, so it is not divisible by 141.
   
• 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 to 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 3 if the sum of its digits is a multiple of 3.
   
• Multiples: Multiples are the results we get after multiplying a number by an integer. For example, multiples of 141 are 141, 282, 423, 564, etc.
   
• Integers: Integers are the numbers that include all the whole numbers, negative numbers, and zero.
   
• Subtraction: Subtraction is the process of finding out the difference between two numbers by reducing one number from another.
   
• Verification: The process of confirming the accuracy of a result, often by using an alternative method such as division.
