What are the Factors of -168?

The numbers that divide -168 evenly are known as factors of -168.

 

A factor of -168 is a number that divides the number without remainder.

 

The factors of 168 are 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, and 168.

 

Negative factors of -168: -1, -2, -3, -4, -6, -7, -8, -12, -14, -21, -24, -28, -42, -56, -84, and -168.

 

Prime factors of 168: 2, 3, and 7.

 

Prime factorization of 168: 23 × 3 × 7.

 

The sum of factors of 168: 1 + 2 + 3 + 4 + 6 + 7 + 8 + 12 + 14 + 21 + 24 + 28 + 42 + 56 + 84 + 168 = 504

How to Find Factors of -168?

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 168. Identifying the numbers which are multiplied to get the number 168 is the multiplication method.

 

Step 1: Multiply 168 by 1, 168 × 1 = 168.

 

Step 2: Check for other numbers that give 168 after multiplying

 

2 × 84 = 168

3 × 56 = 168

4 × 42 = 168

6 × 28 = 168

7 × 24 = 168

8 × 21 = 168

12 × 14 = 168

 

Therefore, the positive factor pairs of 168 are: (1, 168), (2, 84), (3, 56), (4, 42), (6, 28), (7, 24), (8, 21), (12, 14).

 

For every positive factor, there is a 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 168 by 1, 168 ÷ 1 = 168.

 

Step 2: Continue dividing 168 by the numbers until the remainder becomes 0.

 

168 ÷ 1 = 168

168 ÷ 2 = 84

168 ÷ 3 = 56

168 ÷ 4 = 42

168 ÷ 6 = 28

168 ÷ 7 = 24

168 ÷ 8 = 21

168 ÷ 12 = 14

 

Therefore, the factors of 168 are: 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168.

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

 

168 ÷ 2 = 84

84 ÷ 2 = 42

42 ÷ 2 = 21

21 ÷ 3 = 7

7 ÷ 7 = 1

 

The prime factors of 168 are 2, 3, and 7.

 

The prime factorization of 168 is: 2^3 × 3 × 7.

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, 168 is divided by 2 to get 84.

 

Step 2: Now divide 84 by 2 to get 42.

 

Step 3: Then divide 42 by 2 to get 21.

 

Step 4: Divide 21 by 3 to get 7. Here, 7 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 168 is: 23 × 3 × 7.

 

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 168: (1, 168), (2, 84), (3, 56), (4, 42), (6, 28), (7, 24), (8, 21), (12, 14).

 

Negative factor pairs of -168: (-1, -168), (-2, -84), (-3, -56), (-4, -42), (-6, -28), (-7, -24), (-8, -21), (-12, -14).

Common Mistakes and How to Avoid Them in Factors of -168

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 -168, 1 and -168 are also factors.
