Factors are the numbers that divide any given number evenly without a remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 2021, how they are used in real life, and tips to learn them quickly.

What are the Factors of 2021?

The numbers that divide 2021 evenly are known as factors of 2021.

A factor of 2021 is a number that divides the number without a remainder.

The factors of 2021 are 1, 43, 47, and 2021.

Negative factors of 2021: -1, -43, -47, and -2021.

Prime factors of 2021: 43 and 47.

Prime factorization of 2021: 43 × 47.

The sum of factors of 2021: 1 + 43 + 47 + 2021 = 2112

How to Find Factors of 2021?

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

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 2021. Identifying the numbers which are multiplied to get the number 2021 is the multiplication method.

Step 1: Multiply 2021 by 1, 2021 × 1 = 2021.

Step 2: Check for other numbers that give 2021 after multiplying 43 × 47 = 2021

Therefore, the positive factor pairs of 2021 are: (1, 2021) and (43, 47).

All these factor pairs result in 2021.

For every positive factor, there is a negative factor.

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 2021 by 1, 2021 ÷ 1 = 2021.

Step 2: Continue dividing 2021 by the numbers until the remainder becomes 0.

2021 ÷ 1 = 2021

2021 ÷ 43 = 47

2021 ÷ 47 = 43

Therefore, the factors of 2021 are: 1, 43, 47, and 2021.

Prime Factors and Prime Factorization

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

Using Prime Factorization: In this process, prime factors of 2021 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

2021 ÷ 43 = 47

47 ÷ 47 = 1

The prime factors of 2021 are 43 and 47.

The prime factorization of 2021 is: 43 × 47.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows 

Step 1: Firstly, 2021 is divided by 43 to get 47.

Step 2: Now divide 47 by 47 to get 1. Here, both 43 and 47 are prime numbers and cannot be divided anymore.

So, the prime factorization of 2021 is: 43 × 47.

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 2021: (1, 2021) and (43, 47).

Negative factor pairs of 2021: (-1, -2021) and (-43, -47).

Common Mistakes and How to Avoid Them in Factors of 2021

Problem 1

There are 43 friends and 2021 candies. How will they divide it equally?

Okay, lets begin

They will get 47 candies each.

Explanation

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

2021/43 = 47

Problem 2

A rectangular billboard has a width of 43 meters and a total area of 2021 square meters. Find the length.

Okay, lets begin

47 meters.

Explanation

To find the length of the billboard, we use the formula,

Area = length × width

2021 = length × 43

To find the value of length, we need to shift 43 to the left side.

2021/43 = length

Length = 47.
