What are the Factors of 771?

The numbers that divide 771 evenly are known as factors of 771.

 

A factor of 771 is a number that divides the number without a remainder.

 

The factors of 771 are 1, 3, 257, and 771.

 

Negative factors of 771: -1, -3, -257, and -771.

 

Prime factors of 771: 3 and 257.

 

Prime factorization of 771: 3 × 257.

 

The sum of factors of 771: 1 + 3 + 257 + 771 = 1032

How to Find Factors of 771?

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 771. Identifying the numbers which are multiplied to get the number 771 is the multiplication method.

 

Step 1: Multiply 771 by 1, 771 × 1 = 771.

 

Step 2: Check for other numbers that give 771 after multiplying 3 × 257 = 771

 

Therefore, the positive factor pairs of 771 are: (1, 771) and (3, 257). All these factor pairs result in 771.

 

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 as whole numbers as factors. Factors can be calculated by following a simple division method

 

Step 1: Divide 771 by 1, 771 ÷ 1 = 771.

 

Step 2: Continue dividing 771 by the numbers until the remainder becomes 0.
771 ÷ 1 = 771
771 ÷ 3 = 257

 

Therefore, the factors of 771 are: 1, 3, 257, 771.

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

771 ÷ 3 = 257
257 is a prime number and cannot be divided further.

 

The prime factors of 771 are 3 and 257.

 

The prime factorization of 771 is: 3 × 257.

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, 771 is divided by 3 to get 257.

 

Here, 257 is a prime number and cannot be divided anymore.

 

So, the prime factorization of 771 is: 3 × 257.

 

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 771: (1, 771) and (3, 257).

 

Negative factor pairs of 771: (-1, -771) and (-3, -257).

Common Mistakes and How to Avoid Them in Factors of 771

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 771, 1 and 771 are also factors.

Problem 1

There are 3 friends and 771 marbles. How will they divide it equally?

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

They will get 257 marbles each.

Explanation

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

771/3 = 257

Problem 2

A parking area is rectangular, the length of the area is 3 meters and the total area is 771 square meters. Find the width?

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

257 meters.

Explanation

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

Area = length × width

771 = 3 × width

To find the value of width, we need to shift 3 to the left side.

771/3 = width

Width = 257.
