3 <p>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.</p>

4 <h2>What is the Divisibility Rule of 143?</h2>

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

6 <p><strong>Step 1:</strong>Separate the last three digits<a>of</a>the number. Here in 2145, the last three digits are 145. </p>

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

8 <p><strong>Step 3:</strong>Since 141 is not a<a>multiple</a>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. </p>

9 <h2>Tips and Tricks for Divisibility Rule of 143</h2>

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

11 <ul><li><strong>Know the multiples of 143:</strong>Memorize the multiples of 143 (143, 286, 429, 572, ... etc.) to quickly check divisibility. If the result from the<a>subtraction</a>is a multiple of 143, then the number is divisible by 143. </li>

12 <li><strong>Repeat the process for large numbers:</strong>Students should keep repeating the divisibility process until they reach a small number that is divisible by 143. <p>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.</p>

13 </li>

14 <li><strong>Use the division method to verify: </strong>Students can use the division method as a way to verify and crosscheck their results. This will help them to verify and also learn. </li>

15 </ul><h2>Common Mistakes and How to Avoid Them in Divisibility Rule of 143</h2>

16 <p>The divisibility rule of 143 helps us to quickly check if the given number is divisible by 143, but common mistakes like calculation errors lead to incorrect calculations. Here we will understand some common mistakes that will help you to understand. </p>

20 <p>Is 429 divisible by 143?</p>

21 <p>Okay, lets begin</p>

22 <p>Yes, 429 is divisible by 143.</p>

23 <h3>Explanation</h3>

24 <p>To check if 429 is divisible by 143, we can use the standard division method:</p>

25 <p> 1) Divide the number 429 by 143. </p>

26 <p>2) The result is 3, with a remainder of 0. </p>

27 <p>Therefore, 429 is divisible by 143.</p>

28 <p>Well explained 👍</p>

29 <h3>Problem 2</h3>

30 <p>Check the divisibility rule of 143 for 572.</p>

31 <p>Okay, lets begin</p>

32 <p>Yes, 572 is divisible by 143. </p>

33 <h3>Explanation</h3>

34 <p>To determine if 572 is divisible by 143, use the following process: </p>

35 <p>1) Divide 572 by 143. </p>

36 <p>2) The quotient is 4, and the remainder is 0. </p>

37 <p>Since the remainder is 0, 572 is divisible by 143.</p>

38 <p>Well explained 👍</p>

39 <h3>Problem 3</h3>

40 <p>Is -286 divisible by 143?</p>

41 <p>Okay, lets begin</p>

42 <p>Yes, -286 is divisible by 143. </p>

43 <h3>Explanation</h3>

44 <p>To check if -286 is divisible by 143, remove the negative sign and proceed with division:</p>

45 <p> 1) Divide 286 by 143. </p>

46 <p>2) The result is 2 with a remainder of 0. </p>

47 <p>Therefore, -286 is divisible by 143.</p>

48 <p>Well explained 👍</p>

49 <h3>Problem 4</h3>

50 <p>Can 125 be divisible by 143 following the divisibility rule?</p>

51 <p>Okay, lets begin</p>

52 <p>No, 125 isn't divisible by 143.</p>

53 <h3>Explanation</h3>

54 <p>To verify if 125 is divisible by 143, perform the division: </p>

55 <p>1) Divide 125 by 143. </p>

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

57 <p>Therefore, 125 is not divisible by 143.</p>
