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 791, how they are used in real life, and tips to learn them quickly.

What are the Factors of 791?

The numbers that divide 791 evenly are known as factors of 791.

A factor of 791 is a number that divides the number without remainder.

The factors of 791 are 1, 13, 61, and 791.

Negative factors of 791: -1, -13, -61, and -791.

Prime factors of 791: 13 and 61.

Prime factorization of 791: 13 × 61.

The sum of factors of 791: 1 + 13 + 61 + 791 = 866

How to Find Factors of 791?

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 791. Identifying the numbers which are multiplied to get the number 791 is the multiplication method.

Step 1: Multiply 791 by 1, 791 × 1 = 791.

Step 2: Check for other numbers that give 791 after multiplying 13 × 61 = 791

Therefore, the positive factor pairs of 791 are: (1, 791) and (13, 61).

All these factor pairs result in 791.

For every positive factor, there is a negative factor.

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 791 by 1, 791 ÷ 1 = 791.

Step 2: Continue dividing 791 by the numbers until the remainder becomes 0.

791 ÷ 1 = 791

791 ÷ 13 = 61

Therefore, the factors of 791 are: 1, 13, 61, 791.

Prime Factors and Prime Factorization

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

Using Prime Factorization: In this process, prime factors of 791 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

791 ÷ 13 = 61

61 ÷ 61 = 1

The prime factors of 791 are 13 and 61.

The prime factorization of 791 is: 13 × 61.

Factor Tree

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

Step 1: Firstly, 791 is divided by 13 to get 61.

Step 2: Divide 61 by 61 to get 1. Here, 61 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 791 is: 13 × 61.

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 791: (1, 791) and (13, 61).

Negative factor pairs of 791: (-1, -791) and (-13, -61).

Common Mistakes and How to Avoid Them in Factors of 791

Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.

Problem 1

There are 791 pieces of candy and 61 children. How will they divide it equally?

Okay, lets begin

They will get 13 candies each.

Explanation

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

791/61 = 13

Well explained 👍

Problem 2

A garden is rectangular, the length of the garden is 13 meters, and the total area is 791 square meters. Find the width?

Okay, lets begin

61 meters.

Explanation

To find the width of the garden, we use the formula, Area = length × width

791 = 13 × width

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

791/13 = width

Width = 61.
