The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share the items equally, to group or arrange items, and schedule events. In this topic, we will learn about the GCF of 26 and 52.

What is the GCF of 26 and 52?

The greatest common factor of 26 and 52 is 26. The largest divisor of two or more numbers is called the GCF of the number.

If two numbers are co-prime, they have no common factors other than 1, so their GCF is 1. The GCF of two numbers cannot be negative because divisors are always positive.

How to find the GCF of 26 and 52?

To find the GCF of 26 and 52, a few methods are described below -

  1. Listing Factors
  2. Prime Factorization
  3. Long Division Method / by Euclidean Algorithm

GCF of 26 and 52 by Using Listing of Factors

Steps to find the GCF of 26 and 52 using the listing of factors

Step 1: Firstly, list the factors of each number Factors of 26 = 1, 2, 13, 26. Factors of 52 = 1, 2, 4, 13, 26, 52.

Step 2: Now, identify the common factors of them Common factors of 26 and 52: 1, 2, 13, 26.

Step 3: Choose the largest factor The largest factor that both numbers have is 26. The GCF of 26 and 52 is 26.

GCF of 26 and 52 Using Prime Factorization

To find the GCF of 26 and 52 using the Prime Factorization Method, follow these steps:

Step 1: Find the prime factors of each number

Prime Factors of 26: 26 = 2 x 13

Prime Factors of 52: 52 = 2 x 2 x 13 = 2² x 13

Step 2: Now, identify the common prime factors The common prime factors are: 2 x 13

Step 3: Multiply the common prime factors 2 x 13 = 26.

The Greatest Common Factor of 26 and 52 is 26.

GCF of 26 and 52 Using Division Method or Euclidean Algorithm Method

Find the GCF of 26 and 52 using the division method or Euclidean Algorithm Method. Follow these steps:

Step 1: First, divide the larger number by the smaller number Here, divide 52 by 26 52 ÷ 26 = 2 (quotient), The remainder is calculated as 52 − (26×2) = 0

The remainder is zero, so the divisor becomes the GCF. The GCF of 26 and 52 is 26.

Common Mistakes and How to Avoid Them in GCF of 26 and 52

Finding the GCF of 26 and 52 looks simple, but students often make mistakes while calculating the GCF. Here are some common mistakes to be avoided by the students.

Problem 1

A gardener has 26 rose bushes and 52 tulip bulbs. She wants to plant them in equal rows, using the largest number of plants per row. How many plants will be in each row?

Okay, lets begin

We should find the GCF of 26 and 52 GCF of 26 and 52 2 x 13 = 26.

There are 26 equal groups 26 ÷ 26 = 1 52 ÷ 26 = 2

There will be 26 groups, and each group gets 1 rose bush and 2 tulip bulbs.

Explanation

As the GCF of 26 and 52 is 26, the gardener can make 26 rows. Now divide 26 and 52 by 26. Each row gets 1 rose bush and 2 tulip bulbs.

Problem 2

A baker has 26 loaves of whole wheat bread and 52 loaves of sourdough bread. They want to display them in shelves with the same number of loaves on each shelf, using the largest possible number of loaves per shelf. How many loaves will be on each shelf?

Okay, lets begin

GCF of 26 and 52 2 x 13 = 26. So each shelf will have 26 loaves.

Explanation

There are 26 whole wheat and 52 sourdough loaves. To find the total number of loaves on each shelf, we should find the GCF of 26 and 52. There will be 26 loaves on each shelf.

Problem 3

A ribbon maker has 26 meters of red ribbon and 52 meters of blue ribbon. She wants to cut both ribbons into pieces of equal length, using the longest possible length. What should be the length of each piece?

Okay, lets begin

For calculating the longest equal length, we have to calculate the GCF of 26 and 52 The GCF of 26 and 52 2 x 13 = 26. The ribbon is 26 meters long.

Explanation

For calculating the longest length of the ribbon, first, we need to calculate the GCF of 26 and 52, which is 26. The length of each piece of the ribbon will be 26 meters.

Well explained 👍

Problem 4

A carpenter has two wooden planks, one 26 cm long and the other 52 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?

Okay, lets begin

The carpenter needs the longest piece of wood GCF of 26 and 52 2 x 13 = 26. The longest length of each piece is 26 cm.

Explanation

To find the longest length of each piece of the two wooden planks, 26 cm and 52 cm, respectively, we have to find the GCF of 26 and 52, which is 26 cm. The longest length of each piece is 26 cm.

Well explained 👍

Problem 5

If the GCF of 26 and ‘b’ is 26, and the LCM is 104, find ‘b’.

Okay, lets begin

The value of ‘b’ is 52.

Explanation

GCF x LCM = product of the numbers 26 × 104 = 26 × b 2704 = 26b b = 2704 ÷ 26 = 52
