Factors are the numbers that divide any given number evenly without 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 1421, how they are used in real life, and tips to learn them quickly.

What are the Factors of 1421?

The numbers that divide 1421 evenly are known as factors of 1421.

A factor of 1421 is a number that divides the number without remainder.

The factors of 1421 are 1, 13, 109, and 1421.

Negative factors of 1421: -1, -13, -109, and -1421.

Prime factors of 1421: 13 and 109.

Prime factorization of 1421: 13 × 109.

The sum of factors of 1421: 1 + 13 + 109 + 1421 = 1544

How to Find Factors of 1421?

Factors can be found using different methods. Mentioned below are some commonly used methods:

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1421. Identifying the numbers that are multiplied to get the number 1421 is the multiplication method.

Step 1: Multiply 1421 by 1, 1421 × 1 = 1421.

Step 2: Check for other numbers that give 1421 after multiplying 13 × 109 = 1421

Therefore, the positive factor pairs of 1421 are: (1, 1421), (13, 109).

All these factor pairs result in 1421.

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 1421 by 1, 1421 ÷ 1 = 1421.

Step 2: Continue dividing 1421 by the numbers until the remainder becomes 0.

1421 ÷ 1 = 1421

1421 ÷ 13 = 109

1421 ÷ 109 = 13

1421 ÷ 1421 = 1

Therefore, the factors of 1421 are: 1, 13, 109, 1421.

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: In this process, prime factors of 1421 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1421 ÷ 13 = 109

109 ÷ 109 = 1

The prime factors of 1421 are 13 and 109.

The prime factorization of 1421 is: 13 × 109.

Factor Tree

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

Step 1: Firstly, 1421 is divided by 13 to get 109.

Step 2: Now divide 109 by 109 to get 1. Here, 109 is the smallest prime number that cannot be divided anymore.

So, the prime factorization of 1421 is: 13 × 109.

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 1421: (1, 1421), (13, 109).

Negative factor pairs of 1421: (-1, -1421), (-13, -109).

Common Mistakes and How to Avoid Them in Factors of 1421

Problem 1

There are 13 friends and 1421 candies. How will they divide it equally?

Okay, lets begin

They will get 109 candies each.

Explanation

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

1421/13 = 109

Well explained 👍

Problem 2

A field is rectangular, the length of the field is 13 meters, and the total area is 1421 square meters. Find the width?

Okay, lets begin

109 meters.

Explanation

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

Area = length × width

1421 = 13 × width

To find the value of width, we need to shift 13 to the left side.

1421/13 = width

Width = 109.
