What are the Factors of 775?

The numbers that divide 775 evenly are known as factors of 775.

 

A factor of 775 is a number that divides the number without a remainder.

 

The factors of 775 are 1, 5, 25, 31, 155, and 775.

 

Negative factors of 775: -1, -5, -25, -31, -155, and -775.

 

Prime factors of 775: 5 and 31.

 

Prime factorization of 775: 5 × 31 × 5.

 

The sum of factors of 775: 1 + 5 + 25 + 31 + 155 + 775 = 992

How to Find Factors of 775?

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 775. Identifying the numbers which are multiplied to get the number 775 is the multiplication method.

 

Step 1: Multiply 775 by 1, 775 × 1 = 775.

 

Step 2: Check for other numbers that give 775 after multiplying: 5 × 155 = 775 25 × 31 = 775

 

Therefore, the positive factor pairs of 775 are: (1, 775), (5, 155), and (25, 31).

 

For every positive factor, there is a negative factor.

Professor Greenline from BrightChamps

Finding Factors Using Division Method

Dividing the given number with 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 775 by 1, 775 ÷ 1 = 775.

 

Step 2: Continue dividing 775 by the numbers until the remainder becomes 0.

 

775 ÷ 1 = 775

775 ÷ 5 = 155

775 ÷ 25 = 31

 

Therefore, the factors of 775 are: 1, 5, 25, 31, 155, and 775.

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 775 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

 

775 ÷ 5 = 155

155 ÷ 5 = 31

31 ÷ 31 = 1

 

The prime factors of 775 are 5 and 31.

 

The prime factorization of 775 is: 5 × 5 × 31.

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, 775 is divided by 5 to get 155.

 

Step 2: Now divide 155 by 5 to get 31.

 

Step 3: Here, 31 is a prime number that cannot be divided anymore. So, the prime factorization of 775 is: 5 × 5 × 31.

 

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 775: (1, 775), (5, 155), and (25, 31).

 

Negative factor pairs of 775: (-1, -775), (-5, -155), and (-25, -31).

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 775, 1 and 775 are also factors.

Problem 1

A farmer has 775 apples and wants to pack them into crates, with each crate holding 5 apples. How many crates does he need?

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

He will need 155 crates.

Explanation

To pack the apples equally, we need to divide the total apples by the number of apples per crate.

 

775/5 = 155

Problem 2

A rectangular garden has a length of 25 meters, and the total area is 775 square meters. Find the width.

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

31 meters.

Explanation

To find the width of the garden, we use the formula,

 

Area = length × width

 

775 = 25 × width

 

To find the value of width, we need to shift 25 to the left side.

 

775/25 = width

 

Width = 31.

Problem 3

There are 31 rooms in a hotel and 775 guests. How many guests will be in each room if they are distributed equally?

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

Each room will have 25 guests.

Explanation

To find the guests in each room, divide the total guests by the number of rooms.

 

775/31 = 25
