Factors of 831
Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 831, how they are used in real life, and the tips to learn them quickly.
What are the Factors of 831?
The numbers that divide 831 evenly are known as factors of 831. A factor of 831 is a number that divides the number without remainder. The factors of 831 are 1, 3, 277, and 831.
Negative factors of 831: -1, -3, -277, and -831.
Prime factors of 831: 3 and 277.
Prime factorization of 831: 3 × 277.
The sum of factors of 831: 1 + 3 + 277 + 831 = 1112
How to Find Factors of 831?
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
Finding Factors Using Multiplication
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 831. Identifying the numbers which are multiplied to get the number 831 is the multiplication method.
Step 1: Multiply 831 by 1, 831 × 1 = 831.
Step 2: Check for other numbers that give 831 after multiplying
3 × 277 = 831
Therefore, the positive factor pairs of 831 are: (1, 831) and (3, 277). All these factor pairs result in 831. 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 the simple division method -
Step 1: Divide 831 by 1, 831 ÷ 1 = 831.
Step 2: Continue dividing 831 by the numbers until the remainder becomes 0.
831 ÷ 1 = 831
831 ÷ 3 = 277
Therefore, the factors of 831 are: 1, 3, 277, 831.
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 831 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
831 ÷ 3 = 277
277 ÷ 277 = 1
The prime factors of 831 are 3 and 277. The prime factorization of 831 is: 3 × 277.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 831 is divided by 3 to get 277.
Step 2: Now divide 277 by 277 to get 1. So, the prime factorization of 831 is: 3 × 277.
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 831: (1, 831) and (3, 277).
- Negative factor pairs of 831: (-1, -831) and (-3, -277).
Common Mistakes and How to Avoid Them in Factors of 831
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 831, 1 and 831 are also factors.
Factors of 831 Examples
Problem 1
There are 3 friends and 831 marbles. How will they divide it equally?
They will get 277 marbles each.
Explanation
To divide the marbles equally, we need to divide the total marbles by the number of friends.
831/3 = 277
Problem 2
A rectangular garden has a width of 3 meters and the total area is 831 square meters. Find the length.
The length is 277 meters.
Explanation
To find the length of the garden, we use the formula,
Area = length × width
831 = length × 3
To find the value of length, we need to shift 3 to the left side.
831/3 = length
Length = 277.
Problem 3
There are 831 apples and 277 baskets. How many apples will be in each basket?
Each basket will have 3 apples.
Explanation
To find the apples in each basket, divide the total apples by the baskets.
831/277 = 3
Problem 4
In a class, there are 831 students, and 3 buses. How many students are there in each bus?
There are 277 students in each bus.
Explanation
Dividing the students by the total buses, we will get the number of students in each bus.
831/3 = 277
Problem 5
831 books need to be arranged in 277 shelves. How many books will go on each shelf?
Each of the shelves has 3 books.
Explanation
Divide total books by shelves.
831/277 = 3
