What are the Factors of 800?

The numbers that divide 800 evenly are known as factors of 800.

 

A factor of 800 is a number that divides the number without a remainder.

 

The factors of 800 are 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, and 800.

 

Negative factors of 800: -1, -2, -4, -5, -8, -10, -16, -20, -25, -32, -40, -50, -80, -100, -160, -200, -400, and -800.

 

Prime factors of 800: 2 and 5.

 

Prime factorization of 800: 25 × 52.

 

The sum of factors of 800: 1 + 2 + 4 + 5 + 8 + 10 + 16 + 20 + 25 + 32 + 40 + 50 + 80 + 100 + 160 + 200 + 400 + 800 = 2047

How to Find Factors of 800?

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 the pairs of numbers that are multiplied to give 800. Identifying the numbers which are multiplied to get the number 800 is the multiplication method.

 

Step 1: Multiply 800 by 1, 800 × 1 = 800.

 

Step 2: Check for other numbers that give 800 after multiplying:

2 × 400 = 800

4 × 200 = 800

5 × 160 = 800

8 × 100 = 800

10 × 80 = 800

16 × 50 = 800

20 × 40 = 800

25 × 32 = 800

 

Therefore, the positive factor pairs of 800 are: (1, 800), (2, 400), (4, 200), (5, 160), (8, 100), (10, 80), (16, 50), (20, 40), (25, 32).

 

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 800 by 1, 800 ÷ 1 = 800.

 

Step 2: Continue dividing 800 by the numbers until the remainder becomes 0.

800 ÷ 1 = 800

800 ÷ 2 = 400

800 ÷ 4 = 200

800 ÷ 5 = 160

800 ÷ 8 = 100

800 ÷ 10 = 80

800 ÷ 16 = 50

800 ÷ 20 = 40

800 ÷ 25 = 32

 

Therefore, the factors of 800 are: 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800.

Prime Factors and Prime Factorization

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

 

  • Using prime factorization
     
  • Using a factor tree

 

Using Prime Factorization: In this process, prime factors of 800 divide the number to break it down in the multiplication form of prime factors until the remainder becomes 1.

800 ÷ 2 = 400

400 ÷ 2 = 200

200 ÷ 2 = 100

100 ÷ 2 = 50

50 ÷ 2 = 25

25 ÷ 5 = 5

5 ÷ 5 = 1

 

The prime factors of 800 are 2 and 5.

 

The prime factorization of 800 is: 25 × 52.

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, 800 is divided by 2 to get 400.

 

Step 2: Now divide 400 by 2 to get 200.

 

Step 3: Then divide 200 by 2 to get 100.

 

Step 4: Divide 100 by 2 to get 50.

 

Step 5: Divide 50 by 2 to get 25.

 

Step 6: Divide 25 by 5 to get 5. Here, 5 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 800 is: 25 × 52.

 

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 800: (1, 800), (2, 400), (4, 200), (5, 160), (8, 100), (10, 80), (16, 50), (20, 40), (25, 32).

 

Negative factor pairs of 800: (-1, -800), (-2, -400), (-4, -200), (-5, -160), (-8, -100), (-10, -80), (-16, -50), (-20, -40), (-25, -32).

Common Mistakes and How to Avoid Them in Factors of 800

Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and 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 800, 1 and 800 are also factors.
