What are the Factors of 1449?
The numbers that divide 1449 evenly are known as factors of 1449.
A factor of 1449 is a number that divides the number without remainder.
The factors of 1449 are 1, 3, 7, 21, 69, 207, 483, and 1449.
Negative factors of 1449: -1, -3, -7, -21, -69, -207, -483, and -1449.
Prime factors of 1449: 3 and 7.
Prime factorization of 1449: 3 × 7 × 69.
The sum of factors of 1449: 1 + 3 + 7 + 21 + 69 + 207 + 483 + 1449 = 2240
How to Find Factors of 1449?
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 1449. Identifying the numbers which are multiplied to get the number 1449 is the multiplication method.
Step 1: Multiply 1449 by 1, 1449 × 1 = 1449.
Step 2: Check for other numbers that give 1449 after multiplying
3 × 483 = 1449
7 × 207 = 1449
21 × 69 = 1449
Therefore, the positive factor pairs of 1449 are: (1, 1449), (3, 483), (7, 207), (21, 69).
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 1449 by 1, 1449 ÷ 1 = 1449.
Step 2: Continue dividing 1449 by the numbers until the remainder becomes 0.
1449 ÷ 1 = 1449
1449 ÷ 3 = 483
1449 ÷ 7 = 207
1449 ÷ 21 = 69
Therefore, the factors of 1449 are: 1, 3, 7, 21, 69, 207, 483, 1449.
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 a factor tree
Using Prime Factorization: In this process, prime factors of 1449 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1449 ÷ 3 = 483
483 ÷ 3 = 161
161 ÷ 7 = 23
23 is a prime number.
The prime factors of 1449 are 3, 7, and 23.
The prime factorization of 1449 is: 3 × 7 × 23.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1449 is divided by 3 to get 483.
Step 2: Now divide 483 by 3 to get 161.
Step 3: Then divide 161 by 7 to get 23.
23 is a prime number that cannot be divided anymore.
So, the prime factorization of 1449 is: 3 × 7 × 23.
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 1449: (1, 1449), (3, 483), (7, 207), and (21, 69).
Negative factor pairs of 1449: (-1, -1449), (-3, -483), (-7, -207), and (-21, -69).
Common Mistakes and How to Avoid Them in Factors of 1449
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 1449, 1 and 1449 are also factors.
Factors of 1449 Examples
Problem 1
A company has 21 branches and 1449 employees. How many employees will be in each branch if distributed equally?
Each branch will have 69 employees.
Explanation
To distribute the employees equally, we need to divide the total employees by the number of branches.
1449/21 = 69
Problem 2
A rectangular garden has a length of 69 meters and a total area of 1449 square meters. Find the width?
21 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
1449 = 69 × width
To find the value of width, we need to shift 69 to the left side.
1449/69 = width
Width = 21.
Problem 3
There are 69 boxes and 1449 apples. How many apples will be in each box?
Each box will have 21 apples.
Explanation
To find the apples in each box, divide the total apples by the boxes.
1449/69 = 21
Problem 4
In a class, there are 483 students, and 3 groups. How many students are there in each group?
There are 161 students in each group.
Explanation
Dividing the students by the total groups will give the number of students in each group.
483/3 = 161
Problem 5
1449 plants need to be arranged in 7 rows. How many plants will go in each row?
Each row will have 207 plants.
Explanation
Divide total plants by rows.
1449/7 = 207
