<h3>GCF of 648 and 1029 Using Prime Factorization</h3>
20
-
<p>To find the GCF of 648 and 1029 using the Prime Factorization Method, follow these steps:</p>
21
-
<p><strong>Step 1:</strong>Find the<a>prime factors</a>of each number Prime Factors of 648: 648 = 2 x 2 x 2 x 3 x 3 x 3 x 3 = 2^3 x<a>3^4</a>Prime Factors of 1029: 1029 = 3 x 3 x 3 x 19 = 3^3 x 19</p>
22
-
<p><strong>Step 2:</strong>Now, identify the common prime factors The common prime factors are: 3 x 3 x 3 = 3^3</p>
23
-
<p><strong>Step 3:</strong>Multiply the common prime factors 3^3 = 27. The Greatest Common Factor of 648 and 1029 is 81.</p>

<h3>GCF of 648 and 1029 Using Division Method or Euclidean Algorithm Method</h3>
25
-
<p>Find the GCF of 648 and 1029 using the<a>division</a>method or Euclidean Algorithm Method. Follow these steps:</p>
26
-
<p><strong>Step 1:</strong>First, divide the larger number by the smaller number Here, divide 1029 by 648 1029 ÷ 648 = 1 (<a>quotient</a>), The<a>remainder</a>is calculated as 1029 - (648×1) = 381 The remainder is 381, not zero, so continue the process</p>
27
-
<p><strong>Step 2:</strong>Now divide the previous divisor (648) by the previous remainder (381) Divide 648 by 381 648 ÷ 381 = 1 (quotient), remainder = 648 - (381×1) = 267</p>
28
-
<p><strong>Step 3:</strong>Continue the process by dividing 381 by 267 381 ÷ 267 = 1 (quotient), remainder = 381 - (267×1) = 114 Finally, divide 267 by 114 267 ÷ 114 = 2 (quotient), remainder = 267 - (114×2) = 39 Then divide 114 by 39 114 ÷ 39 = 2 (quotient), remainder = 114 - (39×2) = 36</p>
29
-
<p>Finally, divide 39 by 36 39 ÷ 36 = 1 (quotient), remainder = 39 - (36×1) = 3 Then divide 36 by 3 36 ÷ 3 = 12 (quotient), remainder = 0 The remainder is zero, the divisor will become the GCF. The GCF of 648 and 1029 is 81.</p>

<h3>Problem 1</h3>
33
-
<p>A chef has 648 grams of flour and 1029 grams of sugar. She wants to divide them into equal portions using the largest possible weight. How many grams will each portion weigh?</p>
34
-
<p>Okay, lets begin</p>
35
-
<p>We should find the GCF of 648 and 1029 GCF of 648 and 1029 3^3 = 27. There are 81 equal portions. 648 ÷ 81 = 8 1029 ÷ 81 = 12 There will be 81 portions, and each portion weighs 8 grams of flour and 12 grams of sugar.</p>
36
-
<h3>Explanation</h3>
37
-
<p>As the GCF of 648 and 1029 is 81, the chef can make 81 portions.</p>
38
-
<p>Now divide 648 and 1029 by 81.</p>
39
-
<p>Each portion contains 8 grams of flour and 12 grams of sugar.</p>

<h3>Problem 2</h3>
42
-
<p>A gardener has 648 tulip bulbs and 1029 daffodil bulbs. He wants to plant them in rows with the same number of bulbs in each row, using the largest possible number of bulbs per row. How many bulbs will be in each row?</p>
43
-
<p>Okay, lets begin</p>
44
-
<p>GCF of 648 and 1029 3^3 = 27. So each row will have 81 bulbs.</p>
45
-
<h3>Explanation</h3>
46
-
<p>There are 648 tulip bulbs and 1029 daffodil bulbs.</p>
47
-
<p>To find the total number of bulbs in each row, we should find the GCF of 648 and 1029.</p>
48
-
<p>There will be 81 bulbs in each row.</p>

<h3>Problem 3</h3>
51
-
<p>A textile company has 648 meters of cotton fabric and 1029 meters of wool fabric. They want to cut both fabrics into pieces of equal length, using the longest possible length. What should be the length of each piece?</p>
52
-
<p>Okay, lets begin</p>
53
-
<p>For calculating the longest equal length, we have to calculate the GCF of 648 and 1029 The GCF of 648 and 1029 3^3 = 27. The fabric is 81 meters long.</p>
54
-
<h3>Explanation</h3>
55
-
<p>For calculating the longest length of the fabric, first, we need to calculate the GCF of 648 and 1029, which is 81.</p>
56
-
<p>The length of each piece of the fabric will be 81 meters.</p>
57
-
<p>Well explained 👍</p>

<h3>Problem 4</h3>
59
-
<p>A carpenter has two wooden planks, one 648 cm long and the other 1029 cm long. He wants to cut them into the longest possible equal pieces, without any wood left over. What should be the length of each piece?</p>
60
-
<p>Okay, lets begin</p>
61
-
<p>The carpenter needs the longest piece of wood GCF of 648 and 1029 3^3 = 27. The longest length of each piece is 81 cm.</p>
62
-
<h3>Explanation</h3>
63
-
<p>To find the longest length of each piece of the two wooden planks, 648 cm and 1029 cm, respectively, we have to find the GCF of 648 and 1029, which is 81 cm.</p>
