What are the Factors of 1040?

The numbers that divide 1040 evenly are known as factors of 1040.

 

A factor of 1040 is a number that divides the number without remainder.

 

The factors of 1040 are 1, 2, 4, 5, 8, 10, 13, 16, 20, 26, 32, 40, 52, 65, 80, 104, 130, 160, 208, 260, 520, and 1040.

 

Negative factors of 1040: -1, -2, -4, -5, -8, -10, -13, -16, -20, -26, -32, -40, -52, -65, -80, -104, -130, -160, -208, -260, -520, and -1040.

 

Prime factors of 1040: 2, 5, and 13.

 

Prime factorization of 1040: 24 × 5 × 13.

 

The sum of factors of 1040: 1 + 2 + 4 + 5 + 8 + 10 + 13 + 16 + 20 + 26 + 32 + 40 + 52 + 65 + 80 + 104 + 130 + 160 + 208 + 260 + 520 + 1040 = 3120

How to Find Factors of 1040?

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 1040. Identifying the numbers which are multiplied to get the number 1040 is the multiplication method.

 

Step 1: Multiply 1040 by 1, 1040 × 1 = 1040.

 

Step 2: Check for other numbers that give 1040 after multiplying

2 × 520 = 1040

4 × 260 = 1040

5 × 208 = 1040

8 × 130 = 1040

10 × 104 = 1040

13 × 80 = 1040

16 × 65 = 1040

20 × 52 = 1040

26 × 40 = 1040

32 × 32.5 = 1040 (not a whole number pair)

 

Therefore, the positive factor pairs of 1040 are: (1, 1040), (2, 520), (4, 260), (5, 208), (8, 130), (10, 104), (13, 80), (16, 65), (20, 52), (26, 40). For every positive factor, there is a negative factor.

Finding Factors Using Division Method

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

 

Step 1: Divide 1040 by 1, 1040 ÷ 1 = 1040.

 

Step 2: Continue dividing 1040 by the numbers until the remainder becomes 0.

1040 ÷ 1 = 1040

1040 ÷ 2 = 520

1040 ÷ 4 = 260

1040 ÷ 5 = 208

1040 ÷ 8 = 130

1040 ÷ 10 = 104

1040 ÷ 13 = 80

1040 ÷ 16 = 65

1040 ÷ 20 = 52

1040 ÷ 26 = 40

 

Therefore, the factors of 1040 are: 1, 2, 4, 5, 8, 10, 13, 16, 20, 26, 32, 40, 52, 65, 80, 104, 130, 160, 208, 260, 520, 1040.

Prime Factors and Prime Factorization

The factors can be found by dividing it with a 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 1040 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1040 ÷ 2 = 520

520 ÷ 2 = 260

260 ÷ 2 = 130

130 ÷ 2 = 65

65 ÷ 5 = 13

13 ÷ 13 = 1

 

The prime factors of 1040 are 2, 5, and 13.

 

The prime factorization of 1040 is: 24 × 5 × 13.

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, 1040 is divided by 2 to get 520.

 

Step 2: Now divide 520 by 2 to get 260.

 

Step 3: Then divide 260 by 2 to get 130.

 

Step 4: Divide 130 by 2 to get 65.

 

Step 5: Divide 65 by 5 to get 13. Here, 13 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1040 is: 24 × 5 × 13.

 

Factor Pairs: Two numbers that are multiplied to give a specific number are called as factor pairs. Both positive and negative factors constitute factor pairs.

 

Positive factor pairs of 1040: (1, 1040), (2, 520), (4, 260), (5, 208), (8, 130), (10, 104), (13, 80), (16, 65), (20, 52), (26, 40).

 

Negative factor pairs of 1040: (-1, -1040), (-2, -520), (-4, -260), (-5, -208), (-8, -130), (-10, -104), (-13, -80), (-16, -65), (-20, -52), (-26, -40).

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 1040, 1 and 1040 are also factors.

Problem 1

There are 13 friends and 1040 apples. How will they divide it equally?

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

They will get 80 apples each.

Explanation

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

 

1040/13 = 80

Problem 2

A field is rectangular, the length of the field is 26 meters, and the total area is 1040 square meters. Find the width?

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

40 meters.

Explanation

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

 

Area = length × width

 

1040 = 26 × width

 

To find the value of width, we need to shift 26 to the left side.

 

1040/26 = width

 

Width = 40.

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

Each bag will have 52 candies.

Explanation

To find the candies in each bag, divide the total candies with the bags.

 

1040/20 = 52
