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 96 and 84.

What is the GCF of 96 and 84?

The greatest common factor of 96 and 84 is 12. The largest divisor of two or more numbers is called the GCF of the numbers.

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 96 and 84?

To find the GCF of 96 and 84, a few methods are described below 

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

GCF of 96 and 84 by Using Listing of factors

GCF of 96 and 84 Using Prime Factorization

To find the GCF of 96 and 84 using the Prime Factorization Method, follow these steps:

Step 1: Find the prime factors of each number Prime Factors of 96: 96 = 2 × 2 × 2 × 2 × 2 × 3 = 2^5 × 3 Prime Factors of 84: 84 = 2 × 2 × 3 × 7 = 2^2 × 3 × 7

Step 2: Now, identify the common prime factors The common prime factors are: 2 × 2 × 3 = 2^2 × 3

Step 3: Multiply the common prime factors 2^2 × 3 = 4 × 3 = 12. The Greatest Common Factor of 96 and 84 is 12.

GCF of 96 and 84 Using Division Method or Euclidean Algorithm Method

Find the GCF of 96 and 84 using the division method or Euclidean Algorithm Method. Follow these steps:

Step 1: First, divide the larger number by the smaller number Here, divide 96 by 84 96 ÷ 84 = 1 (quotient), remainder is calculated as 96 − (84×1) = 12 The remainder is 12, not zero, so continue the process

Step 2: Now divide the previous divisor (84) by the previous remainder (12) Divide 84 by 12 84 ÷ 12 = 7 (quotient), remainder = 84 − (12×7) = 0 The remainder is zero, the divisor will become the GCF. The GCF of 96 and 84 is 12.

Common Mistakes and How to Avoid Them in GCF of 96 and 84

Finding the GCF of 96 and 84 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 chef has 96 apples and 84 oranges. She wants to pack them into equal sets, with the largest number of fruits in each set. How many fruits will be in each set?

Okay, lets begin

We should find the GCF of 96 and 84. GCF of 96 and 84 2^2 × 3 = 4 × 3 = 12. There are 12 equal groups. 96 ÷ 12 = 8 84 ÷ 12 = 7 There will be 12 groups, and each group gets 8 apples and 7 oranges.

Explanation

As the GCF of 96 and 84 is 12, the chef can make 12 groups.

Now divide 96 and 84 by 12.

Each group gets 8 apples and 7 oranges.

Problem 2

A warehouse has 96 large boxes and 84 small boxes. They want to arrange them in rows with the same number of boxes in each row, using the largest possible number of boxes per row. How many boxes will be in each row?

Okay, lets begin

GCF of 96 and 84 2^2 × 3 = 4 × 3 = 12. So each row will have 12 boxes.

Explanation

There are 96 large and 84 small boxes.

To find the total number of boxes in each row, we should find the GCF of 96 and 84.

There will be 12 boxes in each row.

Problem 3

A tailor has 96 meters of cotton fabric and 84 meters of silk fabric. She wants to cut both fabrics 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 96 and 84. The GCF of 96 and 84 2^2 × 3 = 4 × 3 = 12. The fabric is 12 meters long.

Explanation

For calculating the longest length of the fabric, first we need to calculate the GCF of 96 and 84, which is 12.

The length of each piece of the fabric will be 12 meters.

Problem 4

A gardener has two plots of land, one 96 square meters and the other 84 square meters. He wants to divide them into the largest possible equal sections, without any land left over. What should be the area of each section?

Okay, lets begin

The gardener needs the largest section of land. GCF of 96 and 84 2^2 × 3 = 4 × 3 = 12. The largest area of each section is 12 square meters.

Explanation

To find the largest area of each section for the two plots, 96 square meters and 84 square meters, respectively, we have to find the GCF of 96 and 84, which is 12 square meters.

The largest area of each section is 12 square meters.

Problem 5

If the GCF of 96 and ‘b’ is 12, and the LCM is 672, find ‘b’.

Okay, lets begin

The value of ‘b’ is 84.

Explanation

GCF × LCM = product of the numbers

12 × 672

= 96 × b 8064

= 96b b

= 8064 ÷ 96 = 84
