Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 658, how they are used in real life, and the tips to learn them quickly.

What are the Factors of 658?

The numbers that divide 658 evenly are known as factors of 658. A factor of 658 is a number that divides the number without remainder. The factors of 658 are 1, 2, 329, and 658.

Negative factors of 658: -1, -2, -329, and -658.

Prime factors of 658: 2 and 329.

Prime factorization of 658: 2 × 329.

The sum of factors of 658: 1 + 2 + 329 + 658 = 990

How to Find Factors of 658?

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

  1. Finding factors using multiplication
  2. Finding factors using division method
  3. 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 658. Identifying the numbers which are multiplied to get the number 658 is the multiplication method.

Step 1: Multiply 658 by 1, 658 × 1 = 658.

Step 2: Check for other numbers that give 658 after multiplying 2 × 329 = 658

Therefore, the positive factor pairs of 658 are: (1, 658) and (2, 329). All these factor pairs result in 658. 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 658 by 1, 658 ÷ 1 = 658.

Step 2: Continue dividing 658 by the numbers until the remainder becomes 0.

658 ÷ 1 = 658

658 ÷ 2 = 329

Therefore, the factors of 658 are: 1, 2, 329, and 658.

Prime Factors and Prime Factorization

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

Using Prime Factorization: In this process, prime factors of 658 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

658 ÷ 2 = 329

329 is a prime number.

The prime factors of 658 are 2 and 329.

The prime factorization of 658 is: 2 × 329.

Factor Tree

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

Step 1: Firstly, 658 is divided by 2 to get 329. Step 2: 329 is a prime number and cannot be divided further. Therefore, the prime factorization of 658 is: 2 × 329.

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 658: (1, 658) and (2, 329).
  • Negative factor pairs of 658: (-1, -658) and (-2, -329).

Common Mistakes and How to Avoid Them in Factors of 658

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

Download Worksheets

Problem 1

There are 329 apples and 2 boxes. How will they distribute them equally?

Okay, lets begin

They will get 164.5 apples each, but since apples cannot be divided, they cannot be distributed equally without cutting an apple.

Explanation

To divide the apples equally, we need to divide the total apples by the number of boxes.

329/2 = 164.5

Problem 2

A garden is rectangular, the width of the garden is 2 meters, and the total area is 658 square meters. Find the length?

Okay, lets begin

329 meters.

Explanation

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

Area = length × width

658 = length × 2

To find the value of length, we need to shift 2 to the left side.

658/2 = length

Length = 329.

Problem 3

There are 658 marbles and 1 bag. How many marbles will be in the bag?

Okay, lets begin

The bag will have 658 marbles.

Explanation

To find the marbles in the bag, divide the total marbles by the number of bags.

658/1 = 658

Problem 4

In a class, there are 658 students, and 2 groups. How many students are there in each group?

Okay, lets begin

There are 329 students in each group.

Explanation

Dividing the students by the total groups, we will get the number of students in each group.

658/2 = 329

Well explained 👍

Problem 5

658 pages need to be arranged in 1 book. How many pages will go in each book?

Okay, lets begin

All 658 pages will go in the book.

Explanation

Divide total pages by the number of books.

658/1 = 658
