Factors of 397
Factors are the numbers that divide any given number evenly without a 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 397, how they are used in real life, and tips to learn them quickly.
What are the Factors of 397?
The numbers that divide 397 evenly are known as factors of 397.
A factor of 397 is a number that divides without a remainder.
Since 397 is a prime number, its only factors are 1 and 397.
Negative factors of 397: -1 and -397.
Prime factors of 397: 397 (since it is a prime number itself).
Prime factorization of 397: 397 (as it is prime, it is only divisible by itself and 1).
The sum of factors of 397: 1 + 397 = 398
How to Find Factors of 397?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using the division method
- Understanding prime numbers 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 397.
Since 397 is a prime number, it can only be expressed as a product of 1 and itself.
Therefore, the positive factor pair of 397 is: (1, 397).
For every positive factor, there is a corresponding negative factor.
Finding Factors Using Division Method
Dividing the given number with whole numbers until the remainder becomes zero and listing out the numbers that result as whole numbers as factors. Factors can be calculated by the following simple division method:
Step 1: Divide 397 by 1, 397 ÷ 1 = 397.
Since 397 is a prime number, no other whole number divisions will result in a zero remainder except for 397 divided by itself.
Therefore, the factors of 397 are: 1 and 397.
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 factor tree
Using Prime Factorization: Since 397 is prime, its only prime factor is itself.
Thus, the prime factorization of 397 is simply 397.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors.
However, since 397 is a prime number, it cannot be broken down further.
The factor tree for 397 is simply: 397
As 397 is a prime number, the prime factorization of 397 is just 397.
Common Mistakes and How to Avoid Them in Factors of 397
Mistakes are common while finding factors. We can identify and correct these 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, for factors of 397, 1 and 397 are factors.
Factors of 397 Examples
Problem 1
A teacher has 397 stickers and wants to give them to 1 student. How many will each student get?
The student will receive 397 stickers.
Explanation
To divide the stickers equally, we need to divide the total stickers by the number of students.
397/1 = 397
Problem 2
A gardener has 397 plants and wants to plant them in 1 row. How many plants will be in the row?
There will be 397 plants in the row.
Explanation
To find the number of plants in each row, we use the formula:
397/1 = 397
Problem 3
A jeweler has 397 beads and wants to create a necklace with all of them. How many beads will be in the necklace?
The necklace will have 397 beads.
Explanation
To use all the beads in one necklace, divide the total beads by 1.
397/1 = 397
Problem 4
A library has 397 books and wants to distribute them evenly to 1 shelf. How many books will go on the shelf?
The shelf will have 397 books.
Explanation
Dividing the total books by the number of shelves, we will get the number of books on each shelf.
397/1 = 397
Problem 5
There are 1 team and 397 soccer balls. How many soccer balls will each team get?
The team will get 397 soccer balls.
Explanation
Divide the total soccer balls by the number of teams.
397/1 = 397
