<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 78.</p>

<h2>What is the Divisibility Rule of 78?</h2>
5
-
<p>The<a>divisibility rule</a>for 78 is a method by which we can find out if a<a>number</a>is divisible by 78 or not without using the<a>division</a>method. A number is divisible by 78 if it is divisible by both 2 and 39. Let's check whether 624 is divisible by 78 using the divisibility rule.</p>
6
-
<p><strong>Step 1:</strong>Check divisibility by 2. The last digit<a>of</a>624 is 4, which is even, so 624 is divisible by 2.</p>
7
-
<p><strong>Step 2:</strong>Check divisibility by 39. Divide the number into parts that are easy to handle: 624 can be broken into 600 and 24. </p>
8
-
<p>Check if 600 is divisible by 39. 600 ÷ 39 = 15.38, not an<a>integer</a>. Check if 24 is divisible by 39. 24 ÷ 39 = 0.615, not an integer.</p>
9
-
<p>Since 624 is divisible by 2 but not by 39, it is not divisible by 78.</p>

<h3>Problem 1</h3>
21
-
<p>Can 624 be divided evenly by 78?</p>
22
-
<p>Okay, lets begin</p>
23
-
<p>Yes, 624 is divisible by 78.</p>
24
-
<h3>Explanation</h3>
25
-
<p>To determine if 624 is divisible by 78, we can use a simplified approach as 78 is made up of 2, 3, and 13 (since 78 = 2 x 3 x 13). </p>
26
-
<p>1) Check if 624 is divisible by 2: The last digit is 4, which is even, so it's divisible by 2.</p>
27
-
<p>2) Check if 624 is divisible by 3: Sum the digits, 6 + 2 + 4 = 12, which is divisible by 3.</p>
28
-
<p>3) Check if 624 is divisible by 13: Divide 624 by 13 and check if the result is a whole number. 624 ÷ 13 = 48, which is a whole number.</p>
29
-
<p>Since 624 is divisible by 2, 3, and 13, it is divisible by 78.</p>

<h3>Problem 2</h3>
32
-
<p>Determine if 780 is divisible by 78.</p>
33
-
<p>Okay, lets begin</p>
34
-
<p>Yes, 780 is divisible by 78.</p>
35
-
<h3>Explanation</h3>
36
-
<p>To check if 780 is divisible by 78, we can verify the divisibility by its factors.</p>
37
-
<p>1) Check if 780 is divisible by 2: The last digit is 0, which is even, so it's divisible by 2.</p>
38
-
<p>2) Check if 780 is divisible by 3: Sum the digits, 7 + 8 + 0 = 15, which is divisible by 3.</p>
39
-
<p>3) Check if 780 is divisible by 13: Divide 780 by 13 and check if the result is a whole number. 780 ÷ 13 = 60, which is a whole number.</p>
40
-
<p>Since 780 is divisible by 2, 3, and 13, it is divisible by 78.</p>

<h3>Problem 3</h3>
43
-
<p>Is 234 not divisible by 78?</p>
44
-
<p>Okay, lets begin</p>
45
-
<p>No, 234 is not divisible by 78.</p>
46
-
<h3>Explanation</h3>
47
-
<p>To determine if 234 is divisible by 78, check its divisibility by 2, 3, and 13.</p>
48
-
<p>1) Check if 234 is divisible by 2: The last digit is 4, which is even, so it's divisible by 2.</p>
49
-
<p>2) Check if 234 is divisible by 3: Sum the digits, 2 + 3 + 4 = 9, which is divisible by 3.</p>
50
-
<p>3) Check if 234 is divisible by 13: Divide 234 by 13 and check if the result is a whole number. 234 ÷ 13 = 18 with a remainder, which means it's not a whole number.</p>
51
-
<p>Since 234 is not divisible by 13, it is not divisible by 78.</p>
