Factors of 1982
Factors are the numbers that divide any given number evenly without a remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 1982, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1982?
The numbers that divide 1982 evenly are known as factors of 1982.
A factor of 1982 is a number that divides the number without a remainder.
The factors of 1982 are 1, 2, 991, and 1982.
Negative factors of 1982: -1, -2, -991, and -1982.
Prime factors of 1982: 2 and 991.
Prime factorization of 1982: 2 × 991.
The sum of factors of 1982: 1 + 2 + 991 + 1982 = 2976
How to Find Factors of 1982?
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
Finding Factors Using Multiplication
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 1982. Identifying the numbers which are multiplied to get the number 1982 is the multiplication method.
Step 1: Multiply 1982 by 1, 1982 × 1 = 1982.
Step 2: Check for other numbers that give 1982 after multiplying 2 × 991 = 1982
Therefore, the positive factor pairs of 1982 are: (1, 1982) and (2, 991).
All these factor pairs result in 1982.
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 in whole numbers as factors. Factors can be calculated by following a simple division method
Step 1: Divide 1982 by 1, 1982 ÷ 1 = 1982.
Step 2: Continue dividing 1982 by the numbers until the remainder becomes 0.
1982 ÷ 1 = 1982
1982 ÷ 2 = 991
Therefore, the factors of 1982 are: 1, 2, 991, 1982.
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 1982 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1982 ÷ 2 = 991
991 ÷ 991 = 1
The prime factors of 1982 are 2 and 991.
The prime factorization of 1982 is: 2 × 991.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1982 is divided by 2 to get 991. Here, 991 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 1982 is: 2 × 991.
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 1982: (1, 1982) and (2, 991).
Negative factor pairs of 1982: (-1, -1982) and (-2, -991).
Common Mistakes and How to Avoid Them in Factors of 1982
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
Forgetting the number itself and 1 is a factor
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 1982, 1 and 1982 are also factors.
Factors of 1982 Examples
Problem 1
There are 2 buses and 1982 passengers. How will they be divided equally?
Each bus will have 991 passengers.
Explanation
To divide the passengers equally, we need to divide the total passengers by the number of buses.
1982/2 = 991
Problem 2
A rectangular garden has a length of 1982 meters and a total area of 1982 square meters. What is the width?
1 meter.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
1982 = 1982 × width
To find the value of width, we divide the area by the length.
1982/1982 = width
Width = 1.
Problem 3
There are 991 oranges and 2 crates. How many oranges will be in each crate?
Each crate will have 495.5 oranges.
Explanation
To find the oranges in each crate, divide the total oranges by the crates. 991/2 = 495.5 (Note: A fractional answer indicates a need for whole crates, or the context of division should be adjusted.)
Problem 4
In a tournament, there are 1982 participants, and they need to be divided into teams of 2. How many teams will there be?
There will be 991 teams.
Explanation
Dividing the participants by the team size gives the number of teams.
1982/2 = 991
Problem 5
A library has 1982 books and 1 shelf. How many books will go on the shelf?
All 1982 books will go on the shelf.
Explanation
Divide total books by the number of shelves.
1982/1 = 1982
