What are the Factors of 1278?

The numbers that divide 1278 evenly are known as factors of 1278.

 

A factor of 1278 is a number that divides the number without remainder.

 

The factors of 1278 are 1, 2, 3, 6, 11, 17, 22, 33, 34, 51, 66, 102, 187, 374, 639, and 1278.

 

Negative factors of 1278: -1, -2, -3, -6, -11, -17, -22, -33, -34, -51, -66, -102, -187, -374, -639, and -1278.

 

Prime factors of 1278: 2, 3, 11, 17.

 

Prime factorization of 1278: 2 × 3 × 11 × 17.

 

The sum of factors of 1278: 1 + 2 + 3 + 6 + 11 + 17 + 22 + 33 + 34 + 51 + 66 + 102 + 187 + 374 + 639 + 1278 = 2826

How to Find Factors of 1278?

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 1278. Identifying the numbers which are multiplied to get the number 1278 is the multiplication method.

 

Step 1: Multiply 1278 by 1, 1278 × 1 = 1278.

 

Step 2: Check for other numbers that give 1278 after multiplying

 

2 × 639 = 1278

3 × 426 = 1278

6 × 213 = 1278

11 × 116 = 1278

17 × 75 = 1278

22 × 58 = 1278

33 × 38 = 1278

 

Therefore, the positive factor pairs of 1278 are: (1, 1278), (2, 639), (3, 426), (6, 213), (11, 116), (17, 75), (22, 58), (33, 38).

 

All these factor pairs result in 1278.

 

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 result as whole numbers as factors. Factors can be calculated by following a simple division method -

 

Step 1: Divide 1278 by 1, 1278 ÷ 1 = 1278.

 

Step 2: Continue dividing 1278 by the numbers until the remainder becomes 0.

 

1278 ÷ 1 = 1278

1278 ÷ 2 = 639

1278 ÷ 3 = 426

1278 ÷ 6 = 213

1278 ÷ 11 = 116

1278 ÷ 17 = 75

1278 ÷ 22 = 58

1278 ÷ 33 = 38

 

Therefore, the factors of 1278 are: 1, 2, 3, 6, 11, 17, 22, 33, 34, 51, 66, 102, 187, 374, 639, and 1278.

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 1278 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.

 

1278 ÷ 2 = 639

639 ÷ 3 = 213

213 ÷ 3 = 71

71 ÷ 71 = 1

 

The prime factors of 1278 are 2, 3, 11, and 17.

 

The prime factorization of 1278 is: 2 × 3 × 11 × 17.

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, 1278 is divided by 2 to get 639.

 

Step 2: Now divide 639 by 3 to get 213.

 

Step 3: Then divide 213 by 3 to get 71.

 

Step 4: Divide 71 by 71 to get 1.

Here, 71 is the smallest prime number, that cannot be divided anymore.

 

So, the prime factorization of 1278 is: 2 × 3 × 11 × 17.

 

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 1278: (1, 1278), (2, 639), (3, 426), (6, 213), (11, 116), (17, 75), (22, 58), (33, 38).

 

Negative factor pairs of 1278: (-1, -1278), (-2, -639), (-3, -426), (-6, -213), (-11, -116), (-17, -75), (-22, -58), (-33, -38).

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 1278, 1 and 1278 are also factors.

Problem 1

There are 3 siblings and 1278 candies. How will they divide it equally?

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

They will get 426 candies each.

Explanation

To divide the candies equally, we need to divide the total candies with the number of siblings.

 

1278/3 = 426

Problem 2

A rectangular garden has a length of 22 meters and a total area of 1278 square meters. Find the width?

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

58 meters.

Explanation

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

 

Area = length × width

 

1278 = 22 × width

 

To find the value of width, we need to shift 22 to the left side.

 

1278/22 = width

 

Width = 58.
