Factors of -1
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
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 Ă— 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 Ă· 1 = -1. Step 2: Divide -1 by -1, -1 Ă· -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.
Common Mistakes and How to Avoid Them in Factors of -1
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
Mistake 1
Forgetting the number itself and 1 is a factor
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.
Mistake 2
Including Zero as a Factor
Zero cannot be a factor of any number because division by zero is undefined. Always ensure that zero is not mistakenly included as a factor.
Mistake 3
Confusing Factors With Multiples
Factors are numbers that divide the original number without a remainder, whereas multiples are products of the number and an integer. Do not confuse factors of -1 with its multiples.
Mistake 4
Including Non-integers as Factors
Only integers can be factors. Non-integers, such as fractions or decimals, cannot be factors of any integer.
Factors of -1 Examples
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?
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?
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?
The final temperature is -1 degree.
Explanation
The temperature drops by 1 degree, so from 0 degrees, it becomes -1 degree.
