What are the Factors of -144?

The numbers that divide -144 evenly are known as factors of -144.

 

A factor of -144 is a number that divides the number without a remainder.

 

The factors of -144 include both positive and negative numbers: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, and 144, and their negatives: -1, -2, -3, -4, -6, -8, -9, -12, -16, -18, -24, -36, -48, -72, -144.

 

Prime factors of 144: 2 and 3.

 

Prime factorization of 144: 24 × 32.

 

The sum of the positive factors of 144: 1 + 2 + 3 + 4 + 6 + 8 + 9 + 12 + 16 + 18 + 24 + 36 + 48 + 72 + 144 = 403

How to Find Factors of -144?

Factors can be found using different methods. Mentioned below are some commonly used methods:

 

  • Finding factors using multiplication
     
  • Finding factors using the division method
     
  • Prime factors and prime factorization
Professor Greenline from BrightChamps

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify pairs of numbers that are multiplied to give 144. Identifying the numbers that are multiplied to get the number 144 is the multiplication method.

 

Step 1: Multiply 144 by 1, 144 × 1 = 144.

 

Step 2: Check for other numbers that give 144 after multiplying

 

2 × 72 = 144    

3 × 48 = 144     

4 × 36 = 144     

6 × 24 = 144     

8 × 18 = 144     

9 × 16 = 144     

12 × 12 = 144

 

Therefore, the positive factor pairs of 144 are: (1, 144), (2, 72), (3, 48), (4, 36), (6, 24), (8, 18), (9, 16), (12, 12).

 

For every positive factor, there is a negative factor.

Professor Greenline from BrightChamps

Finding Factors Using Division Method

Dividing the given numbers with whole numbers until the remainder becomes zero and listing out the numbers which result in whole numbers as factors. Factors can be calculated by following a simple division method

 

Step 1: Divide 144 by 1, 144 ÷ 1 = 144.

 

Step 2: Continue dividing 144 by the numbers until the remainder becomes 0.

 

144 ÷ 1 = 144

144 ÷ 2 = 72

144 ÷ 3 = 48

144 ÷ 4 = 36

144 ÷ 6 = 24

144 ÷ 8 = 18

144 ÷ 9 = 16

144 ÷ 12 = 12

 

Therefore, the factors of 144 are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144.

Prime Factors and Prime Factorization

The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:

 

  • Using prime factorization
     
  • Using factor tree

 

Using Prime Factorization: In this process, prime factors of 144 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

 

144 ÷ 2 = 72

72 ÷ 2 = 36

36 ÷ 2 = 18

18 ÷ 2 = 9

9 ÷ 3 = 3

3 ÷ 3 = 1

 

The prime factors of 144 are 2 and 3.

 

The prime factorization of 144 is: 2^4 × 3^2.

Professor Greenline from BrightChamps

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following steps show

 

Step 1: Firstly, 144 is divided by 2 to get 72.

 

Step 2: Now divide 72 by 2 to get 36.

 

Step 3: Then divide 36 by 2 to get 18.

 

Step 4: Divide 18 by 2 to get 9.

 

Step 5: Divide 9 by 3 to get 3. Here, 3 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 144 is: 24 × 32.

 

Factor Pairs Two numbers that are multiplied to give a specific number are called factor pairs.

 

Both positive and negative factors constitute factor pairs.

 

Positive factor pairs of 144: (1, 144), (2, 72), (3, 48), (4, 36), (6, 24), (8, 18), (9, 16), and (12, 12).

 

Negative factor pairs of 144: (-1, -144), (-2, -72), (-3, -48), (-4, -36), (-6, -24), (-8, -18), (-9, -16), and (-12, -12).

Common Mistakes and How to Avoid Them in Factors of -144

Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.

Mistake 1

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Forgetting the number itself and 1 is a factor

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Children might forget to add the given number itself and 1 as a factor. The number itself and 1 are factors for every number. Always remember to include 1 and the number itself.

 

For example, in factors of -144, 1 and 144 are also factors.

Problem 1

There are 9 teams and 144 points to distribute. How will they divide it equally?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Each team will get 16 points.

Explanation

To divide the points equally, we need to divide the total points with the number of teams.

 

144/9 = 16

Problem 2

A room is rectangular, the length of the room is 12 meters and the total area is 144 square meters. Find the width.

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

12 meters.

Explanation

To find the width of the room, we use the formula,    

 

 Area = length × width    

 

144 = 12 × width     

 

To find the value of the width, we need to divide 144 by 12.     

 

144/12 = width     

 

Width = 12.

Problem 3

There are 18 boxes and 144 apples. How many apples will be in each box?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

Each box will have 8 apples.

Explanation

To find the apples in each box, divide the total apples with the boxes.     

 

144/18 = 8
