What are the Factors of 1971?

The numbers that divide 1971 evenly are known as factors of 1971.

 

A factor of 1971 is a number that divides the number without a remainder.

 

The factors of 1971 are 1, 3, 657, and 1971.

 

Negative factors of 1971: -1, -3, -657, and -1971.

 

Prime factors of 1971: 3 and 657.

 

Prime factorization of 1971: 3 × 657.

 

The sum of factors of 1971: 1 + 3 + 657 + 1971 = 2632

How to Find Factors of 1971?

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 1971. Identifying the numbers which are multiplied to get the number 1971 is the multiplication method.

 

Step 1: Multiply 1971 by 1, 1971 × 1 = 1971.

 

Step 2: Check for other numbers that give 1971 after multiplying

 

3 × 657 = 1971

 

Therefore, the positive factor pairs of 1971 are: (1, 1971) and (3, 657).

 

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 a simple division method

 

Step 1: Divide 1971 by 1, 1971 ÷ 1 = 1971.

 

Step 2: Continue dividing 1971 by the numbers until the remainder becomes 0.

 

1971 ÷ 1 = 1971

1971 ÷ 3 = 657

 

Therefore, the factors of 1971 are: 1, 3, 657, and 1971.

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 1971 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

 

1971 ÷ 3 = 657

657 ÷ 657 = 1

 

The prime factors of 1971 are 3 and 657.

 

The prime factorization of 1971 is: 3 × 657.

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, 1971 is divided by 3 to get 657. Here, 657 is not a prime number, but since it is a larger component of the factorization, it is left as is. So, the prime factorization of 1971 is: 3 × 657.

 

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 1971: (1, 1971) and (3, 657).

 

Negative factor pairs of 1971: (-1, -1971) and (-3, -657).

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 1971, 1 and 1971 are also factors.

Problem 1

A company has 3 departments and 1971 employees. How many employees are in each department if they are divided equally?

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

Each department will have 657 employees.

Explanation

To divide the employees equally, we need to divide the total employees by the number of departments.

 

1971/3 = 657

Problem 2

A rectangular field has a length of 3 meters and a total area of 1971 square meters. What is the width?

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

657 meters.

Explanation

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

 

Area = length × width

 

1971 = 3 × width

 

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

 

1971/3 = width

 

Width = 657.
