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 -154, how they are used in real life, and tips to learn them quickly.

What are the Factors of -154?

The numbers that divide -154 evenly are known as factors of -154.

A factor of -154 is a number that divides the number without remainder.

The factors of -154 are 1, 2, 7, 11, 14, 22, 77, and 154.

Negative factors of -154: -1, -2, -7, -11, -14, -22, -77, and -154.

Prime factors of -154: 2, 7, and 11.

Prime factorization of -154: -1 × 2 × 7 × 11.

The sum of the absolute values of factors of -154: 1 + 2 + 7 + 11 + 14 + 22 + 77 + 154 = 288.

How to Find Factors of -154?

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 -154. Identifying the numbers which are multiplied to get the number -154 is the multiplication method.

Step 1: Multiply -154 by -1, -154 × -1 = 154.

Step 2: Check for other numbers that give 154 after multiplying

-2 × -77 = 154

-7 × -22 = 154

-11 × -14 = 154

Therefore, the positive factor pairs of 154 are: (1, 154), (2, 77), (7, 22), (11, 14).

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 -154 by -1, -154 ÷ -1 = 154.

Step 2: Continue dividing -154 by the numbers until the remainder becomes 0.

-154 ÷ -1 = 154

-154 ÷ -2 = 77

-154 ÷ -7 = 22

-154 ÷ -11 = 14

Therefore, the factors of -154 are: 1, 2, 7, 11, 14, 22, 77, 154.

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

154 ÷ 2 = 77

77 ÷ 7 = 11

11 ÷ 11 = 1

The prime factors of 154 are 2, 7, and 11.

The prime factorization of -154 is: -1 × 2 × 7 × 11.

Factor Tree

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

Step 1: Firstly, 154 is divided by 2 to get 77.

Step 2: Now divide 77 by 7 to get 11.

Step 3: Divide 11 by 11 to get 1. Here, 11 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of -154 is: -1 × 2 × 7 × 11.

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 -154: (1, 154), (2, 77), (7, 22), (11, 14).

Negative factor pairs of -154: (-1, -154), (-2, -77), (-7, -22), (-11, -14).

Common Mistakes and How to Avoid Them in Factors of -154

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 7 groups of people and -154 apples. If each group takes an equal share of apples, how many apples does each group get?

Okay, lets begin

Each group gets -22 apples.

Explanation

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

-154/7 = -22

Problem 2

A machine produces -154 widgets in 11 hours. How many widgets does it produce per hour?

Okay, lets begin

-14 widgets per hour.

Explanation

To find the production rate per hour, use the formula:

Total widgets = widgets per hour × total hours

-154 = widgets per hour × 11

Widgets per hour = -154/11 = -14

Problem 3

There are -154 candies and 2 boxes. How many candies will be in each box?

Okay, lets begin

Each box will have -77 candies.

Explanation

To find the candies in each box, divide the total candies by the number of boxes.

-154/2 = -77

Well explained 👍

Problem 4

A company has -154 tasks to complete and plans to finish them in 14 days. How many tasks should they complete each day?

Okay, lets begin

-11 tasks each day.

Explanation

Dividing the tasks by the number of days, we will get the number of tasks to complete each day.

-154/14 = -11

Well explained 👍

Problem 5

An artist has -154 units of a special paint and uses it at a rate of 11 units per project. How many projects can the artist complete?

Okay, lets begin

The artist can complete 14 projects.

Explanation

Divide the total paint units by the units used per project.

-154/11 = -14
