Factors of -1

Professor Greenline Explaining Math Concepts

Factors are the numbers that divide any given number evenly without remainder. In daily life, understanding factors helps us in various mathematical tasks. In this topic, we will learn about the factors of -1, their significance, and how to understand them quickly.

What are the Factors of -1?

The numbers that divide -1 evenly are known as factors of -1. A factor of -1 is a number that divides the number without remainder. The factors of -1 are 1 and -1. Prime factors of -1: None, since -1 is not a product of positive prime numbers.

How to Find Factors of -1?

Factors can be found using different methods. Mentioned below are some commonly used methods: Finding factors using multiplication Finding factors using the division method

Professor Greenline from BrightChamps

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give -1. Identifying the numbers which are multiplied to get the number -1 is the multiplication method. Step 1: Consider -1 as the product of 1 and itself, -1 × 1 = -1. Therefore, the factor pairs of -1 are: (1, -1).

Finding Factors Using Division Method

Dividing the given number by whole numbers until the remainder becomes zero helps in identifying factors. Factors of -1 can be calculated by following a simple division method: Step 1: Divide -1 by 1, -1 ÷ 1 = -1. Step 2: Divide -1 by -1, -1 ÷ -1 = 1. Therefore, the factors of -1 are: 1 and -1.

Prime Factors and Prime Factorization

The factors can be found by considering prime numbers, but since -1 does not break down into positive prime factors, it does not have prime factors.

Factor Tree

A factor tree is not applicable to -1 as it is a simple number with only two factors, 1 and -1, which do not break down further into prime factors.

Forgetting the number itself and 1 is a factor

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

It is crucial to remember that the number itself and 1 are factors of every number. For example, in factors of -1, both 1 and -1 are factors.

Problem 1

In a game, a player scores -1 point for every incorrect answer. If a player answers all questions incorrectly and ends up with -1 point, how many incorrect answers did they give?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

They gave 1 incorrect answer.

Explanation

The score of -1 means the player got one question wrong, as each incorrect answer scores -1 point.

Problem 2

A balance scale reads -1 when one side is heavier by 1 unit. If the scale tips to -1, what is the difference in weight between the two sides?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The difference in weight is 1 unit.

Explanation

The scale reading of -1 indicates one side is heavier by 1 unit.

Problem 3

A thermometer shows a temperature drop of -1 degree. If the initial temperature was 0 degrees, what is the final temperature?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

The final temperature is -1 degree.

Explanation

The temperature drops by 1 degree, so from 0 degrees, it becomes -1 degree.
