Divisibility Rule of 143

Professor Greenline Explaining Math Concepts

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 143.

What is the Divisibility Rule of 143?

The divisibility rule for 143 is a method by which we can find out if a number is divisible by 143 or not without using the division method. Check whether 2145 is divisible by 143 with the divisibility rule.
 

Step 1: Separate the last three digits of the number. Here in 2145, the last three digits are 145.
 

Step 2: Subtract this three-digit number from twice the remaining part of the number. In this example, 2 × 2 = 4, and 145 - 4 = 141.
 

Step 3: Since 141 is not a multiple of 143, 2145 is not divisible by 143. If the result from step 2 is a multiple of 143, then the number is divisible by 143.divisibility rule of 143

Tips and Tricks for Divisibility Rule of 143

Learning the divisibility rule will help kids to master division. Let’s learn a few tips and tricks for the divisibility rule of 143.
 

  • Know the multiples of 143: Memorize the multiples of 143 (143, 286, 429, 572, ... etc.) to quickly check divisibility. If the result from the subtraction is a multiple of 143, then the number is divisible by 143.
     
  • Repeat the process for large numbers: Students should keep repeating the divisibility process until they reach a small number that is divisible by 143. 

    For example: Check if 11443 is divisible by 143 using the divisibility test. Separate the last three digits, 443, and subtract it from twice the remaining digits: 2 × 11 = 22, 443 - 22 = 421. Since 421 is not a multiple of 143, 11443 is not divisible by 143.
     
  • 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.

Problem 4

Can 125 be divisible by 143 following the divisibility rule?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

No, 125 isn't divisible by 143.

Explanation

To verify if 125 is divisible by 143, perform the division:  

1) Divide 125 by 143.  

2) The result is less than 1, meaning 125 cannot be divided by 143 without a remainder.  

Therefore, 125 is not divisible by 143.
