What are the Factors of 1978?

The numbers that divide 1978 evenly are known as factors of 1978.

 

A factor of 1978 is a number that divides the number without remainder.

 

The factors of 1978 are 1, 2, 989, and 1978.

 

Negative factors of 1978: -1, -2, -989, and -1978.

 

Prime factors of 1978: 2 and 989.

 

Prime factorization of 1978: 2 × 989.

 

The sum of factors of 1978: 1 + 2 + 989 + 1978 = 2970

How to Find Factors of 1978?

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 1978. Identifying the numbers which are multiplied to get the number 1978 is the multiplication method.

 

Step 1: Multiply 1978 by 1, 1978 × 1 = 1978.

 

Step 2: Check for other numbers that give 1978 after multiplying 2 × 989 = 1978

 

Therefore, the positive factor pairs of 1978 are: (1, 1978) and (2, 989).

 

All these factor pairs result in 1978.

 

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

 

Step 1: Divide 1978 by 1, 1978 ÷ 1 = 1978.

 

Step 2: Continue dividing 1978 by the numbers until the remainder becomes 0.

 

1978 ÷ 1 = 1978

1978 ÷ 2 = 989

 

Therefore, the factors of 1978 are: 1, 2, 989, and 1978.

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 factor tree

 

Using Prime Factorization: In this process, prime factors of 1978 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

 

1978 ÷ 2 = 989

 

989 is a prime number and cannot be divided further by any number except itself and 1.

 

The prime factors of 1978 are 2 and 989.

 

The prime factorization of 1978 is: 2 × 989.

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, 1978 is divided by 2 to get 989. Here, 989 is a prime number and cannot be divided anymore. So, the prime factorization of 1978 is: 2 × 989.

 

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 1978: (1, 1978) and (2, 989).

 

Negative factor pairs of 1978: (-1, -1978) and (-2, -989).

Common Mistakes and How to Avoid Them in Factors of 1978

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 1978, 1 and 1978 are also factors.

Problem 1

There are 2 teams and 1978 participants. How will the participants be divided equally?

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

Each team will have 989 participants.

Explanation

To divide the participants equally, we need to divide the total participants by the number of teams.

 

1978/2 = 989

Problem 2

A rectangular garden has a width of 2 meters and a total area of 1978 square meters. Find the length.

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

989 meters.

Explanation

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

 

Area = length × width

 

1978 = length × 2

 

To find the value of the length, we need to shift 2 to the left side.

 

1978/2 = length

 

Length = 989.

Problem 3

There are 1978 toys to be packed in 989 boxes. How many toys will be in each box?

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

Each box will have 2 toys.

Explanation

To find the toys in each box, divide the total toys by the boxes.

 

1978/989 = 2
