Factors of 1397
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 1397, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1397?
The numbers that divide 1397 evenly are known as factors of 1397.
A factor of 1397 is a number that divides the number without remainder.
The factors of 1397 are 1, 19, 73, and 1397.
Negative factors of 1397: -1, -19, -73, and -1397.
Prime factors of 1397: 19 and 73.
Prime factorization of 1397: 19 × 73.
The sum of factors of 1397: 1 + 19 + 73 + 1397 = 1490
How to Find Factors of 1397?
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 1397. Identifying the numbers which are multiplied to get the number 1397 is the multiplication method.
Step 1: Multiply 1397 by 1, 1397 × 1 = 1397.
Step 2: Check for other numbers that give 1397 after multiplying 19 × 73 = 1397
Therefore, the positive factor pairs of 1397 are: (1, 1397) and (19, 73).
All these factor pairs result in 1397.
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 1397 by 1, 1397 ÷ 1 = 1397.
Step 2: Continue dividing 1397 by the numbers until the remainder becomes 0.
1397 ÷ 1 = 1397
1397 ÷ 19 = 73
Therefore, the factors of 1397 are: 1, 19, 73, 1397.
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 1397 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1397 ÷ 19 = 73
73 ÷ 73 = 1
The prime factors of 1397 are 19 and 73.
The prime factorization of 1397 is: 19 × 73.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1397 is divided by 19 to get 73.
Step 2: Now divide 73 by 73 to get 1. Here, both 19 and 73 are prime numbers that cannot be divided further.
So, the prime factorization of 1397 is: 19 × 73.
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 1397: (1, 1397) and (19, 73).
Negative factor pairs of 1397: (-1, -1397) and (-19, -73).
Common Mistakes and How to Avoid Them in Factors of 1397
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 1397, 1 and 1397 are also factors.
Factors of 1397 Examples
Problem 1
There are 19 students and 1397 pencils. How will they distribute the pencils equally?
They will get 73 pencils each.
Explanation
To divide the pencils equally, we need to divide the total pencils by the number of students.
1397/19 = 73
Problem 2
A garden is rectangular, the width of the garden is 73 meters and the total area is 1397 square meters. Find the length?
19 meters.
Explanation
To find the length of the garden, we use the formula,
Area = length × width
1397 = length × 73
To find the value of length, we need to shift 73 to the left side.
1397/73 = length
Length = 19.
Problem 3
There are 73 boxes and 1397 items. How many items will be in each box?
Each box will have 19 items.
Explanation
To find the items in each box, divide the total items by the boxes.
1397/73 = 19
Problem 4
In a contest, there are 1397 participants, and 19 teams. How many participants are there in each team?
There are 73 participants in each team.
Explanation
Dividing the participants by the total teams, we will get the number of participants in each team.
1397/19 = 73
Problem 5
1397 books need to be arranged in 19 shelves. How many books will go on each shelf?
Each of the shelves has 73 books.
Explanation
Divide total books by shelves.
1397/19 = 73
