What are the Factors of -27?

The numbers that divide -27 evenly are known as factors of -27.

 

A factor of -27 is a number that divides the number without remainder.

 

The factors of -27 are 1, 3, 9, and 27.

 

Negative factors of -27: -1, -3, -9, and -27.

 

Prime factors of -27: 3.

 

Prime factorization of -27: -1 × 3³.

 

The sum of factors of -27: 1 + 3 + 9 + 27 = 40.

How to Find Factors of -27?

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

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

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give -27. Identifying the numbers which are multiplied to get the number -27 is the multiplication method.

 

Step 1: Multiply -27 by -1, -27 × -1 = 27.

 

Step 2: Check for other numbers that give -27 after multiplying

-1 × 27 = -27

-3 × 9 = -27

 

Therefore, the positive factor pairs of -27 are: (1, 27), (3, 9).

 

For every positive factor, there is a corresponding negative factor.

Finding Factors Using Division Method

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

 

Step 1: Divide -27 by -1, -27 ÷ -1 = 27.

 

Step 2: Continue dividing -27 by the numbers until the remainder becomes 0.

-27 ÷ -1 = 27

-27 ÷ -3 = 9

 

Therefore, the factors of -27 are: 1, 3, 9, 27.

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 -27 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

-27 ÷ -3 = 9

9 ÷ 3 = 3

3 ÷ 3 = 1

 

The prime factors of -27 are 3.

 

The prime factorization of -27 is: -1 × 3³.

Professor Greenline from BrightChamps

Factor Tree

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

 

Step 1: Firstly, -27 is divided by -3 to get 9.

 

Step 2: Now divide 9 by 3 to get 3.

 

Step 3: Then divide 3 by 3 to get 1. Here, 3 is the smallest prime number that cannot be divided anymore.

 

So, the prime factorization of -27 is: -1 × 3³.

 

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 -27: (1, 27), (3, 9).

 

Negative factor pairs of -27: (-1, -27), (-3, -9).

Common Mistakes and How to Avoid Them in Factors of -27

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 the factors for every number. Always remember to include 1 and the number itself.

 

For example, in factors of -27, 1 and -27 are also factors.
