Factors of 545
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 545, how they are used in real life, and the tips to learn them quickly.
What are the Factors of 545?
The numbers that divide 545 evenly are known as factors of 545.
A factor of 545 is a number that divides the number without remainder.
The factors of 545 are 1, 5, 109, and 545.
Negative factors of 545: -1, -5, -109, and -545.
Prime factors of 545: 5 and 109.
Prime factorization of 545: 5 × 109.
The sum of factors of 545: 1 + 5 + 109 + 545 = 660
How to Find Factors of 545?
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 545. Identifying the numbers which are multiplied to get the number 545 is the multiplication method.
Step 1: Multiply 545 by 1, 545 × 1 = 545.
Step 2: Check for other numbers that give 545 after multiplying
5 × 109 = 545
Therefore, the positive factor pairs of 545 are: (1, 545), (5, 109).
All these factor pairs result in 545.
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 simple division method -
Step 1: Divide 545 by 1, 545 ÷ 1 = 545.
Step 2: Continue dividing 545 by the numbers until the remainder becomes 0.
545 ÷ 1 = 545
545 ÷ 5 = 109
545 ÷ 109 = 5
Therefore, the factors of 545 are: 1, 5, 109, 545.
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 545 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
545 ÷ 5 = 109
109 ÷ 109 = 1
The prime factors of 545 are 5 and 109.
The prime factorization of 545 is: 5 × 109.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 545 is divided by 5 to get 109.
Step 2: Now divide 109 by 109 to get 1.
Here, 109 is a prime number, and it cannot be divided further.
So, the prime factorization of 545 is: 5 × 109.
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 545: (1, 545), (5, 109).
Negative factor pairs of 545: (-1, -545), (-5, -109).
Common Mistakes and How to Avoid Them in Factors of 545
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 factors for every number. Always remember to include 1 and the number itself.
For example, in factors of 545, 1 and 545 are also factors.
Factors of 545 Examples
Problem 1
A gardener has 545 seeds and wants to plant them in rows of 5. How many rows will be there?
There will be 109 rows.
Explanation
To find the number of rows, divide the total seeds by the number of seeds per row.
545/5 = 109
Problem 2
A park has a walkway that is 5 meters wide and covers a total area of 545 square meters. What is the length of the walkway?
109 meters.
Explanation
To find the length of the walkway, we use the formula,
Area = length × width
545 = length × 5
To find the value of length, shift 5 to the left side.
545/5 = length
Length = 109.
Problem 3
A school has 109 students and needs to distribute 545 notebooks equally. How many notebooks will each student receive?
Each student will receive 5 notebooks.
Explanation
To find the notebooks each student receives, divide the total notebooks by the number of students.
545/109 = 5
Problem 4
A company has 545 units of a product and wants to pack them into boxes of 5 units each. How many boxes will be needed?
109 boxes will be needed.
Explanation
Dividing the total units by the units per box gives the number of boxes.
545/5 = 109
Problem 5
A library has 545 books and wants to arrange them in stacks of 109 books. How many stacks will there be?
There will be 5 stacks.
Explanation
Divide total books by books per stack.
545/109 = 5
