Factors of 2009
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 2009, how they are used in real life, and tips to learn them quickly.
What are the Factors of 2009?
The numbers that divide 2009 evenly are known as factors of 2009.
A factor of 2009 is a number that divides the number without remainder.
The factors of 2009 are 1, 7, 41, 49, 287, and 2009.
Negative factors of 2009: -1, -7, -41, -49, -287, and -2009.
Prime factors of 2009: 7 and 41.
Prime factorization of 2009: 7 × 41 × 7.
The sum of factors of 2009: 1 + 7 + 41 + 49 + 287 + 2009 = 2394
How to Find Factors of 2009?
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 2009. Identifying the numbers which are multiplied to get the number 2009 is the multiplication method.
Step 1: Multiply 2009 by 1, 2009 × 1 = 2009.
Step 2: Check for other numbers that give 2009 after multiplying
7 × 287 = 2009
41 × 49 = 2009
Therefore, the positive factor pairs of 2009 are: (1, 2009), (7, 287), and (41, 49).
All these factor pairs result in 2009.
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 2009 by 1, 2009 ÷ 1 = 2009.
Step 2: Continue dividing 2009 by the numbers until the remainder becomes 0.
2009 ÷ 1 = 2009
2009 ÷ 7 = 287
2009 ÷ 41 = 49
Therefore, the factors of 2009 are: 1, 7, 41, 49, 287, and 2009.
Prime Factors and Prime Factorization
The factors can be found by dividing them by 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 2009 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
2009 ÷ 7 = 287
287 ÷ 7 = 41
The prime factors of 2009 are 7 and 41.
The prime factorization of 2009 is: 7 × 41 × 7.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 2009 is divided by 7 to get 287.
Step 2: Now divide 287 by 7 to get 41. Here, 41 is the smallest prime number, which cannot be divided anymore.
So, the prime factorization of 2009 is: 7 × 41 × 7.
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 2009: (1, 2009), (7, 287), and (41, 49).
Negative factor pairs of 2009: (-1, -2009), (-7, -287), and (-41, -49).
Common Mistakes and How to Avoid Them in Factors of 2009
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 of every number. Always remember to include 1 and the number itself.
For example, in factors of 2009, 1 and 2009 are also factors.
Factors of 2009 Examples
Problem 1
There are 7 teams and 2009 items. How will they divide them equally?
They will get 287 items each.
Explanation
To divide the items equally, we need to divide the total items by the number of teams.
2009/7 = 287
Problem 2
A garden is rectangular, the length of the garden is 49 meters and the total area is 2009 square meters. Find the width?
41 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
2009 = 49 × width
To find the value of width, we need to shift 49 to the left side.
2009/49 = width
Width = 41.
Problem 3
There are 41 boxes and 2009 items. How many items will be in each box?
Each box will have 49 items.
Explanation
To find the items in each box, divide the total items by the number of boxes.
2009/41 = 49
Problem 4
In a concert, there are 2009 attendees, and 7 sections. How many attendees are there in each section?
There are 287 attendees in each section.
Explanation
Dividing the attendees by the total sections, we will get the number of attendees in each section.
2009/7 = 287
Problem 5
2009 plants need to be arranged in 41 rows. How many plants will go in each row?
Each of the rows has 49 plants.
Explanation
Divide the total plants by the rows.
2009/41 = 49
