Factors of 1445
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 1445, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1445?
The numbers that divide 1445 evenly are known as factors of 1445.
A factor of 1445 is a number that divides the number without remainder.
The factors of 1445 are 1, 5, 17, 85, 289, and 1445.
Negative factors of 1445: -1, -5, -17, -85, -289, and -1445.
Prime factors of 1445: 5 and 17.
Prime factorization of 1445: 5 × 17².
The sum of factors of 1445: 1 + 5 + 17 + 85 + 289 + 1445 = 1842
How to Find Factors of 1445?
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 1445. Identifying the numbers which are multiplied to get the number 1445 is the multiplication method.
Step 1: Multiply 1445 by 1, 1445 × 1 = 1445.
Step 2: Check for other numbers that give 1445 after multiplying
5 × 289 = 1445
17 × 85 = 1445
Therefore, the positive factor pairs of 1445 are: (1, 1445), (5, 289), and (17, 85).
All these factor pairs result in 1445.
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 1445 by 1, 1445 ÷ 1 = 1445.
Step 2: Continue dividing 1445 by the numbers until the remainder becomes 0.
1445 ÷ 1 = 1445
1445 ÷ 5 = 289
1445 ÷ 17 = 85
Therefore, the factors of 1445 are: 1, 5, 17, 85, 289, 1445.
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 1445 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1445 ÷ 5 = 289
289 ÷ 17 = 17
17 ÷ 17 = 1
The prime factors of 1445 are 5 and 17.
The prime factorization of 1445 is: 5 × 17².
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1445 is divided by 5 to get 289.
Step 2: Now divide 289 by 17 to get 17.
Here, 17 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 1445 is: 5 × 17².
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 1445: (1, 1445), (5, 289), and (17, 85).
Negative factor pairs of 1445: (-1, -1445), (-5, -289), and (-17, -85).
Common Mistakes and How to Avoid Them in Factors of 1445
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 1445, 1 and 1445 are also factors.
Factors of 1445 Examples
Problem 1
There are 17 teams in a tournament and 1445 total points. How will the points be distributed equally among the teams?
Each team will receive 85 points.
Explanation
To distribute the points equally, we need to divide the total points by the number of teams.
1445/17 = 85
Problem 2
A garden plot is rectangular, the length of the plot is 17 meters, and the total area is 289 square meters. Find the width?
17 meters.
Explanation
To find the width of the plot, we use the formula,
Area = length × width
289 = 17 × width
To find the value of width, we need to shift 17 to the left side.
289/17 = width
Width = 17.
Problem 3
There are 289 students in a college and 1445 books. How many books will each student receive if distributed equally?
Each student will receive 5 books.
Explanation
To find the books each student will get, divide the total books by the students.
1445/289 = 5
Problem 4
In a factory, there are 5 production lines, and each line produces 289 units. How many total units are produced?
1445 units are produced.
Explanation
Multiplying the units produced by each line with the number of production lines will give us the total units.
5 × 289 = 1445
Problem 5
A library has 1445 books and 85 shelves. How many books will go on each shelf?
Each shelf will have 17 books.
Explanation
Divide total books by shelves.
1445/85 = 17
