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 103.</p>

4 <h2>What is the Divisibility Rule of 103?</h2>

5 <p>The<a>divisibility rule</a>for 103 is a method by which we can find out if a<a>number</a>is divisible by 103 or not without using the<a>division</a>method. Check whether 2060 is divisible by 103 with the divisibility rule. </p>

6 <p><strong>Step 1:</strong>Break the number into blocks<a>of</a>three from the right. Here, in 2060, you have 060 and 2 (consider 2 as 002 for the purpose of the rule). </p>

7 <p><strong>Step 2:</strong>Multiply the block on the furthest right by 1, the next block by 10, and so on in increasing<a>powers</a>of 10. In this example, it would be 060 × 1 + 002 × 10 = 60 + 20 = 80. </p>

8 <p><strong>Step 3:</strong>Check if the<a>sum</a>is a<a>multiple</a>of 103. In this case, 80 is not a multiple of 103, so 2060 is not divisible by 103.</p>

9 <h2>Tips and Tricks for Divisibility Rule of 103</h2>

10 <p>Learning the divisibility rule will help kids master division. Let’s learn a few tips and tricks for the divisibility rule of 103. </p>

11 <ul><li><strong>Know the multiples of 103:</strong>Memorize the multiples of 103 (103, 206, 309, etc.) to quickly check divisibility. If the result from the sum is a multiple of 103, then the number is divisible by 103. </li>

12 <li><strong>Use consistent block sizes:</strong>Ensure each block is of three digits. If necessary, prepend zeros to make it a three-digit block. </li>

13 <li><strong>Repeat the process for large numbers:</strong>Students should keep repeating the divisibility process until they reach a small number. For example, check if 30909 is divisible by 103. Break it into blocks: 909 and 030. Compute: 909 × 1 + 030 × 10 = 909 + 300 = 1209. 1209 is large, so repeat: 209 and 001, which leads to 209 + 10 = 219. Since 219 is a multiple of 103, 30909 is divisible by 103. </li>

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

19 <h3>Problem 1</h3>

20 <p>Is 5159 divisible by 103?</p>

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

22 <p>Yes, 5159 is divisible by 103.</p>

23 <h3>Explanation</h3>

24 <p>To check the divisibility of 5159 by 103:</p>

25 <p>1) Multiply the last digit by 3, 9 × 3 = 27.</p>

26 <p>2) Subtract the result from the remaining digits, 515 - 27 = 488.</p>

27 <p>3) 488 is a multiple of 103 (103 × 4 = 412), so 5159 is divisible by 103.</p>

28 <p>Well explained 👍</p>

29 <h3>Problem 2</h3>

30 <p>Check the divisibility rule of 103 for 8240.</p>

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

32 <p>No, 8240 is not divisible by 103.</p>

33 <h3>Explanation</h3>

34 <p>For checking the divisibility rule of 103 for 8240:</p>

35 <p>1) Multiply the last digit by 3, 0 × 3 = 0.</p>

36 <p>2) Subtract the result from the remaining digits, 824 - 0 = 824.</p>

37 <p>3) 824 is not a multiple of 103, so 8240 is not divisible by 103.</p>

38 <p>Well explained 👍</p>

39 <h3>Problem 3</h3>

40 <p>Is -927 divisible by 103?</p>

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

42 <p>No, -927 is not divisible by 103.</p>

43 <h3>Explanation</h3>

44 <p>To check if -927 is divisible by 103:</p>

45 <p>1) Multiply the last digit by 3, 7 × 3 = 21.</p>

46 <p>2) Subtract the result from the remaining digits, 92 - 21 = 71.</p>

47 <p>3) 71 is not a multiple of 103, so -927 is not divisible by 103.</p>

48 <p>Well explained 👍</p>

49 <h3>Problem 4</h3>

50 <p>Can 2060 be divisible by 103 following the divisibility rule?</p>

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

52 <p>Yes, 2060 is divisible by 103.</p>

53 <h3>Explanation</h3>

54 <p>To check if 2060 is divisible by 103:</p>

55 <p>1) Multiply the last digit by 3, 0 × 3 = 0.</p>
