What are the Factors of 781?

The numbers that divide 781 evenly are known as factors of 781.

 

A factor of 781 is a number that divides the number without remainder.

 

The factors of 781 are 1, 11, 71, and 781.

 

Negative factors of 781: -1, -11, -71, and -781.

 

Prime factors of 781: 11 and 71.

 

Prime factorization of 781: 11 × 71.

 

The sum of factors of 781: 1 + 11 + 71 + 781 = 864

How to Find Factors of 781?

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 781. Identifying the numbers which are multiplied to get the number 781 is the multiplication method.

 

Step 1: Multiply 781 by 1, 781 × 1 = 781.

 

Step 2: Check for other numbers that give 781 after multiplying 11 × 71 = 781

 

Therefore, the positive factor pairs of 781 are: (1, 781) and (11, 71).

 

All these factor pairs result in 781.

 

For every positive factor, there is a negative factor.

Professor Greenline from BrightChamps

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 simple division method

 

Step 1: Divide 781 by 1, 781 ÷ 1 = 781.

 

Step 2: Continue dividing 781 by the numbers until the remainder becomes 0.

 

781 ÷ 1 = 781

781 ÷ 11 = 71

781 ÷ 71 = 11

 

Therefore, the factors of 781 are: 1, 11, 71, and 781.

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

 

781 ÷ 11 = 71

71 ÷ 71 = 1

 

The prime factors of 781 are 11 and 71.

 

The prime factorization of 781 is: 11 × 71.

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, 781 is divided by 11 to get 71.

 

Step 2: Now divide 71 by 71 to get 1. Here, 71 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 781 is: 11 × 71.

 

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 781: (1, 781) and (11, 71).

 

Negative factor pairs of 781: (-1, -781) and (-11, -71).

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 word. Always remember to include 1 and the number itself.

 

For example, in factors of 781, 1 and 781 are also factors.

Factors of 781 Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

There are 11 friends and 781 candies. How will they divide it equally?

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

They will get 71 candies each.

Explanation

To divide the candies equally, we need to divide the total candies with the number of friends.

 

781/11 = 71

Max from BrightChamps Praising Clear Math Explanations

Problem 2

A field is rectangular, the length of the field is 71 meters and the total area is 781 square meters. Find the width?

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

11 meters.

Explanation

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

 

Area = length × width

 

781 = 71 × width

 

To find the value of width, we need to shift 71 to the left side.

 

781/71 = width

 

Width = 11.

Problem 3

There are 71 bags and 781 candies. How many candies will be in each bag?

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

Each bag will have 11 candies.

Explanation

To find the candies in each bag, divide the total candies with the bags.

 

781/71 = 11
