What are the Factors of -38?

The numbers that divide -38 evenly are known as factors of -38.

 

A factor of -38 is a number that divides the number without remainder.

 

The factors of -38 are 1, 2, 19, and 38.

 

Negative factors of -38: -1, -2, -19, and -38.

 

Prime factors of 38: 2 and 19.

 

Prime factorization of 38: 2 × 19.

 

The sum of the positive factors of 38: 1 + 2 + 19 + 38 = 60

How to Find Factors of -38?

Factors can be found using different methods. Mentioned below are some commonly used methods:

 

  • Finding factors using multiplication
     
  • Finding factors using the 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 38. Identifying the numbers which are multiplied to get the number 38 is the multiplication method.

 

Step 1: Multiply 38 by 1, 38 × 1 = 38.

 

Step 2: Check for other numbers that give 38 after multiplying 2 × 19 = 38

 

Therefore, the positive factor pairs of 38 are: (1, 38), (2, 19).

 

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 a simple division method 

 

Step 1: Divide 38 by 1, 38 ÷ 1 = 38.

 

Step 2: Continue dividing 38 by the numbers until the remainder becomes 0.

 

38 ÷ 1 = 38

38 ÷ 2 = 19

 

Therefore, the factors of 38 are: 1, 2, 19, 38.

Professor Greenline from BrightChamps

Prime Factors and Prime Factorization

The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:

 

  • Using prime factorization
     
  • Using a factor tree

 

Using Prime Factorization: In this process, prime factors of 38 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

 

38 ÷ 2 = 19

19 ÷ 19 = 1

 

The prime factors of 38 are 2 and 19.

 

The prime factorization of 38 is: 2 × 19.

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, 38 is divided by 2 to get 19.

 

Step 2: Now, 19 is a prime number and cannot be divided anymore. So, the prime factorization of 38 is: 2 × 19.

 

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 38: (1, 38), (2, 19).

 

Negative factor pairs of -38: (-1, -38), (-2, -19).

Common Mistakes and How to Avoid Them in Factors of -38

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 -38, 1 and 38 are also factors.

Problem 1

A charity has 38 boxes of food and wants to distribute them equally among 2 shelters. How many boxes will each shelter receive?

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

Each shelter will receive 19 boxes.

Explanation

To divide the boxes equally, we need to divide the total boxes by the number of shelters.

38/2 = 19

Problem 2

A small garden is divided into 38 equal sections, with each section occupying 2 square meters. What is the total area of the garden?

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

76 square meters.

Explanation

To find the total area, multiply the number of sections by the area of each section.

38 × 2 = 76

Problem 3

A school has 19 classes, and each class has the same number of students. If there are 38 students in total, how many students are in each class?

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

Each class has 2 students.

Explanation

To find the number of students in each class, divide the total students by the number of classes.

38/19 = 2

Problem 4

38 chairs need to be arranged in 1 row for a performance. How many chairs will be in the row?

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

There will be 38 chairs in the row.

Explanation

Since there is 1 row, all the chairs will be in that row.

38/1 = 38

Problem 5

A librarian wants to arrange 2 books on each shelf. If there are 19 shelves, how many books are needed?

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

38 books are needed.

Explanation

To find the total number of books, multiply the number of shelves by the number of books per shelf.

19 × 2 = 38
