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 -99, how they are used in real life, and the tips to learn them quickly.

What are the Factors of -99?

The numbers that divide -99 evenly are known as factors of -99.

A factor of -99 is a number that divides the number without remainder.

The positive factors of -99 are 1, 3, 9, 11, 33, and 99.

Negative factors of -99: -1, -3, -9, -11, -33, and -99.

Prime factors of -99: 3 and 11.

Prime factorization of 99: 3² × 11.

The sum of the absolute values of factors of -99: 1 + 3 + 9 + 11 + 33 + 99 = 156

How to Find Factors of -99?

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 -99. Identifying the numbers which are multiplied to get the number -99 is the multiplication method.

Step 1: Multiply -99 by 1, -99 × 1 = -99.

Step 2: Check for other numbers that give -99 after multiplying:

3 × -33 = -99

9 × -11 = -99

Therefore, the positive factor pairs of -99 are: (1, -99), (3, -33), and (9, -11).

All these factor pairs result in -99.

For every positive factor, there is a corresponding negative factor.

Finding Factors Using Division Method

Dividing the given number 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 -99 by 1, -99 ÷ 1 = -99.

Step 2: Continue dividing -99 by the numbers until the remainder becomes 0.

-99 ÷ 1 = -99

-99 ÷ 3 = -33

-99 ÷ 9 = -11

-99 ÷ 11 = -9

-99 ÷ 33 = -3

Therefore, the factors of -99 are: 1, 3, 9, 11, 33, 99, and their negative counterparts.

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 -99 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

99 ÷ 3 = 33

33 ÷ 3 = 11

11 ÷ 11 = 1

The prime factors of 99 are 3 and 11.

The prime factorization of 99 is 3² × 11.

Factor Tree

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

Step 1: First, divide 99 by 3 to get 33.

Step 2: Now divide 33 by 3 to get 11. Here, 11 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 99 is 3² × 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 -99: (1, -99), (3, -33), and (9, -11).

Negative factor pairs of -99: (-1, 99), (-3, 33), and (-9, 11).

Common Mistakes and How to Avoid Them in Factors of -99

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 11 teams and -99 points to distribute equally. How many points will each team receive?

Okay, lets begin

Each team will get -9 points.

Explanation

To divide the points equally, we need to divide the total points by the number of teams.

-99/11 = -9

Well explained 👍

Problem 2

A garden plot is rectangular, the length of the plot is 9 meters, and the total area is -99 square meters. Find the width?

Okay, lets begin

-11 meters.

Explanation

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

Area = length × width

-99 = 9 × width

To find the value of width, divide -99 by 9.

-99/9 = -11

Well explained 👍

Problem 3

There are 3 containers and -99 liters of liquid. How many liters will be in each container?

Okay, lets begin

Each container will have -33 liters.

Explanation

To find the liters in each container, divide the total liters by the number of containers.

-99/3 = -33

Well explained 👍

Problem 4

In a class, there are 33 students, and -99 assignments to complete. How many assignments should each student do?

Okay, lets begin

Each student should do -3 assignments.

Explanation

Dividing the assignments by the total number of students, we get the number of assignments each student should do.

-99/33 = -3

Well explained 👍

Problem 5

-99 tasks need to be divided among 9 workers. How many tasks will each worker handle?

Okay, lets begin

Each worker will handle -11 tasks.

Explanation

Divide the total tasks by the number of workers.

-99/9 = -11
