What are the Factors of 1515?

The numbers that divide 1515 evenly are known as factors of 1515.

 

A factor of 1515 is a number that divides the number without remainder.

 

The factors of 1515 are 1, 3, 5, 101, 303, 505, and 1515.

 

Negative factors of 1515: -1, -3, -5, -101, -303, -505, and -1515.

 

Prime factors of 1515: 3, 5, and 101.

 

Prime factorization of 1515: 3 × 5 × 101.

 

The sum of factors of 1515: 1 + 3 + 5 + 101 + 303 + 505 + 1515 = 2433

How to Find Factors of 1515?

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 1515. Identifying the numbers which are multiplied to get the number 1515 is the multiplication method.

 

Step 1: Multiply 1515 by 1, 1515 × 1 = 1515.

 

Step 2: Check for other numbers that give 1515 after multiplying

3 × 505 = 1515

5 × 303 = 1515

 

Therefore, the positive factor pairs of 1515 are: (1, 1515), (3, 505), and (5, 303). All these factor pairs result in 1515.

 

For every positive factor, there is a negative factor.

Professor Greenline from BrightChamps

Finding Factors Using Division Method

Dividing the given numbers with the 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 1515 by 1, 1515 ÷ 1 = 1515.

 

Step 2: Continue dividing 1515 by the numbers until the remainder becomes 0.

1515 ÷ 1 = 1515

1515 ÷ 3 = 505

1515 ÷ 5 = 303

1515 ÷ 101 = 15

 

Therefore, the factors of 1515 are: 1, 3, 5, 101, 303, 505, and 1515.

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
     
  • Using factor tree

 

Using Prime Factorization: In this process, prime factors of 1515 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1515 ÷ 3 = 505

505 ÷ 5 = 101

101 ÷ 101 = 1

 

The prime factors of 1515 are 3, 5, and 101.

 

The prime factorization of 1515 is: 3 × 5 × 101.

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, 1515 is divided by 3 to get 505.

 

Step 2: Now divide 505 by 5 to get 101. Here, 101 is a prime number, that cannot be divided anymore. So, the prime factorization of 1515 is: 3 × 5 × 101.

 

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 1515: (1, 1515), (3, 505), and (5, 303).

 

Negative factor pairs of 1515: (-1, -1515), (-3, -505), and (-5, -303).

Common Mistakes and How to Avoid Them in Factors of 1515

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 the factors for every number. Always remember to include 1 and the number itself.

 

For example, in factors of 1515, 1 and 1515 are also factors.

Factors of 1515 Examples

Ray, the Character from BrightChamps Explaining Math Concepts
Max, the Girl Character from BrightChamps

Problem 1

A concert hall has 1515 seats and 505 rows. How many seats are there in each row?

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

There will be 3 seats in each row.

Explanation

To find out how many seats are in each row, we need to divide the total seats by the number of rows.

1515/505 = 3

Problem 2

A rectangular garden has a length of 5 meters and the total area is 1515 square meters. What is the width of the garden?

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

303 meters.

Explanation

To find the width of the garden, we use the formula, Area = length × width

1515 = 5 × width

To find the value of width, we need to shift 5 to the left side.

1515/5 = width

Width = 303.

Problem 3

A school is organizing 1515 books into 101 sections. How many books will be in each section?

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

There will be 15 books in each section.

Explanation

To find the number of books in each section, divide the total books by the sections.

1515/101 = 15
