Factors of -25

Professor Greenline Explaining Math Concepts

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 -25, how they are used in real life, and tips to learn them quickly.

What are the Factors of -25?

The numbers that divide -25 evenly are known as factors of -25.

 

A factor of -25 is a number that divides the number without remainder.

 

The factors of 25 are 1, 5, and 25.

 

Negative factors of 25: -1, -5, and -25.

 

Prime factors of 25: 5.

 

Prime factorization of 25: (52).

 

The sum of factors of 25: 1 + 5 + 25 = 31

How to Find Factors of -25?

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
     
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 25. Identifying the numbers which are multiplied to get the number 25 is the multiplication method.

 

Step 1: Multiply 25 by 1, 25 × 1 = 25.

 

Step 2: Check for other numbers that give 25 after multiplying 5 × 5 = 25

 

Therefore, the positive factor pairs of 25 are: (1, 25) and (5, 5).

 

All these factor pairs result in 25. For every positive factor, there is a negative factor.

Professor Greenline from BrightChamps

Finding Factors Using Division Method

Dividing the given numbers with whole numbers until the remainder becomes zero and listing out the numbers which result in whole numbers as factors. Factors can be calculated by following the simple division method

Step 1: Divide 25 by 1, 25 ÷ 1 = 25.

Step 2: Continue dividing 25 by the numbers until the remainder becomes 0.

 

25 ÷ 1 = 25

 

25 ÷ 5 = 5

 

Therefore, the factors of 25 are: 1, 5, 25.

 

Thus, the factors of -25 include -1, -5, -25.

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
  • Using factor tree

 

Using Prime Factorization: In this process, prime factors of 25 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

 

25 ÷ 5 = 5

5 ÷ 5 = 1

 

The prime factor of 25 is 5.

 

The prime factorization of 25 is: (52).

Professor Greenline from BrightChamps

Factor Tree

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

 

Step 1: Firstly, 25 is divided by 5 to get 5.

 

Step 2: Now divide 5 by 5 to get 1. Here, 5 is the prime number that cannot be divided anymore.

 

So, the prime factorization of 25 is: (52).

 

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 25: (1, 25) and (5, 5).

 

Negative factor pairs of -25: (-1, -25) and (-5, -5).

Common Mistakes and How to Avoid Them in Factors of -25

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

Red Cross Icon Indicating Mistakes to Avoid in This Math Topic

Forgetting the number itself and 1 is a factor

Green Checkmark Icon Indicating Correct Solutions in This Math Topic

Children might forget to add the given number itself and 1 as a factor. The number itself and 1 are factors for every number. Always remember to include 1 and the number itself.

 

For example, in factors of -25, 1, and -25 are also factors.

Problem 1

There are 5 friends and 25 apples. How will they divide them equally?

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

They will get 5 apples each.

Explanation

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

 

25/5 = 5

Problem 2

A garden is square-shaped, and the total area is 25 square meters. What is the length of each side?

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

5 meters.

Explanation

For a square, the area is calculated as: Area = side × side

 

25 = side × side

 

To find the side length, we find the square root of 25.

 

The side = 5.

Problem 3

There are 25 chairs to be arranged in 5 rows. How many chairs will be in each row?

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

Each row will have 5 chairs.

Explanation

To find the number of chairs in each row, divide the total chairs by the number of rows.

 

25/5 = 5
