What are the Factors of 817?

The numbers that divide 817 evenly are known as factors of 817.

 

A factor of 817 is a number that divides the number without a remainder.

 

The factors of 817 are 1, 19, 43, and 817.

 

Negative factors of 817: -1, -19, -43, and -817.

 

Prime factors of 817: 19 and 43.

 

Prime factorization of 817: 19 × 43.

 

The sum of factors of 817: 1 + 19 + 43 + 817 = 880

How to Find Factors of 817?

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 817. Identifying the numbers which are multiplied to get the number 817 is the multiplication method.

 

Step 1: Multiply 817 by 1, 817 × 1 = 817.

 

Step 2: Check for other numbers that give 817 after multiplying

19 × 43 = 817

 

Therefore, the positive factor pairs of 817 are: (1, 817) and (19, 43).

 

All these factor pairs result in 817.

 

For every positive factor, there is a negative factor.

Professor Greenline from BrightChamps

Finding Factors Using Division Method

Dividing the given number with 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 a simple division method

 

Step 1: Divide 817 by 1, 817 ÷ 1 = 817.

 

Step 2: Continue dividing 817 by numbers until the remainder becomes 0.

817 ÷ 1 = 817

817 ÷ 19 = 43

817 ÷ 43 = 19

 

Therefore, the factors of 817 are: 1, 19, 43, 817.

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

 

817 ÷ 19 = 43

43 ÷ 43 = 1

 

The prime factors of 817 are 19 and 43.

 

The prime factorization of 817 is: 19 × 43.

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, 817 is divided by 19 to get 43.

 

Step 2: Now divide 43 by 43 to get 1. Here, 43 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 817 is: 19 × 43.

 

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 817: (1, 817) and (19, 43).

 

Negative factor pairs of 817: (-1, -817) and (-19, -43).

Common Mistakes and How to Avoid Them in Factors of 817

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 817, 1 and 817 are also factors.

Problem 1

There are 19 students and 817 apples. How will they divide it equally?

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

They will get 43 apples each.

Explanation

To divide the apples equally, we need to divide the total apples by the number of students.

817/19 = 43

Problem 2

A rectangular field has a length of 43 meters and a total area of 817 square meters. Find the width.

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

19 meters.

Explanation

To find the width of the field, we use the formula, Area = length × width

817 = 43 × width

To find the value of width, we need to move 43 to the left side.

817/43 = width

Width = 19.

Problem 3

There are 43 baskets and 817 oranges. How many oranges will be in each basket?

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

Each basket will have 19 oranges.

Explanation

To find the oranges in each basket, divide the total oranges by the baskets.

817/43 = 19
