The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share items equally, to group or arrange items, and to schedule events. In this topic, we will learn about the GCF of 32 and 36.

What is the GCF of 32 and 36?

The greatest common factor of 32 and 36 is 4. 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 32 and 36?

To find the GCF of 32 and 36, a few methods are described below:

  • Listing Factors
  • Prime Factorization
  • Long Division Method / by Euclidean Algorithm

GCF of 32 and 36 by Using Listing of Factors

Steps to find the GCF of 32 and 36 using the listing of factors:

Step 1: Firstly, list the factors of each number:

Factors of 32 = 1, 2, 4, 8, 16, 32.

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, 36.

Step 2: Now, identify the common factors of them.

Common factors of 32 and 36: 1, 2, 4.

Step 3: Choose the largest factor:

The largest factor that both numbers have is 4.

The GCF of 32 and 36 is 4.

GCF of 32 and 36 Using Prime Factorization

To find the GCF of 32 and 36 using the Prime Factorization Method, follow these steps:

Step 1: Find the prime factors of each number:

Prime Factors of 32: 32 = 2 × 2 × 2 × 2 × 2 = 25

Prime Factors of 36: 36 = 2 × 2 × 3 × 3 = 22 × 32

Step 2: Now, identify the common prime factors.

The common prime factors are: 2 × 2 = 22

Step 3: Multiply the common prime factors 22 = 4.

The Greatest Common Factor of 32 and 36 is 4.

GCF of 32 and 36 Using Division Method or Euclidean Algorithm Method

Find the GCF of 32 and 36 using the division method or Euclidean Algorithm Method. Follow these steps:

Step 1: First, divide the larger number by the smaller number

Here, divide 36 by 32 36 ÷ 32 = 1 (quotient), The remainder is calculated as 36 − (32×1) = 4

The remainder is 4, not zero, so continue the process

Step 2: Now divide the previous divisor (32) by the previous remainder (4)

Divide 32 by 4 32 ÷ 4 = 8 (quotient), remainder = 32 − (4×8) = 0

The remainder is zero, the divisor will become the GCF.

The GCF of 32 and 36 is 4.

Common Mistakes and How to Avoid Them in GCF of 32 and 36

Finding the GCF of 32 and 36 seems 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 32 flower pots and 36 seeds. She wants to distribute them into the largest number of equal groups. How many items will be in each group?

Okay, lets begin

We should find the GCF of 32 and 36 GCF of 32 and 36

22 = 4.

There are 4 equal groups

32 ÷ 4 = 8

36 ÷ 4 = 9

There will be 4 groups, and each group gets 8 flower pots and 9 seeds.

Explanation

As the GCF of 32 and 36 is 4, the gardener can make 4 groups.

Now divide 32 and 36 by 4.

Each group gets 8 flower pots and 9 seeds.

Problem 2

A school has 32 red chairs and 36 blue chairs. They want to arrange them in rows with the same number of chairs in each row, using the largest possible number of chairs per row. How many chairs will be in each row?

Okay, lets begin

GCF of 32 and 36 22 = 4. So each row will have 4 chairs.

Explanation

There are 32 red and 36 blue chairs.

To find the total number of chairs in each row, we should find the GCF of 32 and 36.

There will be 4 chairs in each row.

Problem 3

A tailor has 32 meters of red ribbon and 36 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 32 and 36

The GCF of 32 and 36 22 = 4.

The ribbon is 4 meters long.

Explanation

For calculating the longest length of the ribbon, first, we need to calculate the GCF of 32 and 36, which is 4. The length of each piece of the ribbon will be 4 meters.

Problem 4

A carpenter has two wooden planks, one 32 cm long and the other 36 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 32 and 36

22 = 4.

The longest length of each piece is 4 cm.

Explanation

To find the longest length of each piece of the two wooden planks, 32 cm and 36 cm, respectively, we have to find the GCF of 32 and 36, which is 4 cm. The longest length of each piece is 4 cm.

Problem 5

If the GCF of 32 and ‘a’ is 4, and the LCM is 288. Find ‘a’.

Okay, lets begin

The value of ‘a’ is 36.

Explanation

GCF × LCM = product of the numbers

4 × 288 = 32 × a

1152 = 32a

a = 1152 ÷ 32 = 36
