Factors of 581
Factors are the numbers that divide any given number evenly without 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 581, how they are used in real life, and tips to learn them quickly.
What are the Factors of 581?
The numbers that divide 581 evenly are known as factors of 581.
A factor of 581 is a number that divides the number without remainder.
The factors of 581 are 1, 7, 83, and 581.
Negative factors of 581: -1, -7, -83, and -581.
Prime factors of 581: 7 and 83.
Prime factorization of 581: 7 × 83.
The sum of factors of 581: 1 + 7 + 83 + 581 = 672
How to Find Factors of 581?
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 581. Identifying the numbers which are multiplied to get the number 581 is the multiplication method.
Step 1: Multiply 581 by 1, 581 × 1 = 581.
Step 2: Check for other numbers that give 581 after multiplying 7 × 83 = 581
Therefore, the positive factor pairs of 581 are: (1, 581) and (7, 83). For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given numbers with 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 581 by 1, 581 ÷ 1 = 581.
Step 2: Continue dividing 581 by the numbers until the remainder becomes 0.
581 ÷ 1 = 581
581 ÷ 7 = 83
581 ÷ 83 = 7
Therefore, the factors of 581 are: 1, 7, 83, and 581.
Prime Factors and Prime Factorization
The factors can be found by dividing 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 581 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
581 ÷ 7 = 83
83 ÷ 83 = 1
The prime factors of 581 are 7 and 83.
The prime factorization of 581 is: 7 × 83.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 581 is divided by 7 to get 83.
Step 2: Now divide 83 by 83 to get 1. Here, 83 is a prime number, and it cannot be divided further. So, the prime factorization of 581 is: 7 × 83.
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 581: (1, 581) and (7, 83).
Negative factor pairs of 581: (-1, -581) and (-7, -83).
Common Mistakes and How to Avoid Them in Factors of 581
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 581, 1 and 581 are also factors.
Factors of 581 Examples
Problem 1
A farmer has 581 apples and wants to pack them in boxes of 7 apples each. How many complete boxes can he pack?
He can pack 83 complete boxes.
Explanation
To find the number of complete boxes, divide the total apples by the number of apples per box.
581/7 = 83
Problem 2
A rectangular garden has a length of 83 meters and an area of 581 square meters. Find the width?
7 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
581 = 83 × width
To find the value of width, we need to shift 83 to the left side.
581/83 = width
Width = 7.
Problem 3
There are 581 passengers and 83 buses. How many passengers will be in each bus?
Each bus will have 7 passengers.
Explanation
To find the passengers in each bus, divide the total passengers by the number of buses.
581/83 = 7
Problem 4
A company has 581 units of product to distribute equally among 7 distribution centers. How many units will each center receive?
Each center will receive 83 units.
Explanation
Dividing the units by the total distribution centers, we will get the number of units for each center.
581/7 = 83
Problem 5
581 chairs need to be arranged in 83 rows. How many chairs will go in each row?
Each row will have 7 chairs.
Explanation
Divide the total chairs by the rows.
581/83 = 7
