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 389, how they are used in real life, and tips to learn them quickly.
The numbers that divide 389 evenly are known as factors of 389. A factor of 389 is a number that divides the number without remainder.
The factors of 389 are 1 and 389.
Negative factors of 389: -1 and -389.
Prime factors of 389: 389.
Prime factorization of 389: 389 is a prime number, so it cannot be factored further.
The sum of factors of 389: 1 + 389 = 390
Factors can be found using different methods. Mentioned below are some commonly used methods:
To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 389. Since 389 is a prime number, it only has trivial multiplication pairs.
Step 1: Multiply 389 by 1, 389 × 1 = 389. Therefore, the positive factor pairs of 389 are: (1, 389). For every positive factor, there is a negative factor.
Dividing the given number 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 389 by 1, 389 ÷ 1 = 389.
Step 2: Check divisibility by other numbers up to the square root of 389 (~19.7). Since 389 is a prime number, it is not divisible by any other whole numbers except itself and 1. Therefore, the factors of 389 are: 1 and 389.
The factors can be found by dividing it with a prime number. Since 389 is a prime number, it cannot be broken down into smaller prime factors.
Using Prime Factorization: In this process, we divide 389 by itself as it is a prime number, leaving no further prime factors.
The factor tree is a graphical representation of breaking down any number into prime factors. However, since 389 is a prime number, it cannot be broken down further. So, the prime factorization of 389 is: 389.
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 389: (1, 389).
Negative factor pairs of 389: (-1, -389).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
There are 389 trees in a park, and they are to be grouped equally into 1 group. How many trees will be in the group?
The group will have 389 trees.
Since there is only one group, all trees will be in that group.
A classroom has 389 chairs and needs to be divided equally into 389 rows. How many chairs will be in each row?
1 chair.
To divide the chairs equally, we divide the total chairs by the number of rows.
389/389 = 1
A library has 389 books. If each shelf holds 1 book, how many shelves are needed?
389 shelves.
To find the number of shelves needed, divide the total books by the number of books per shelf.
389/1 = 389
A theater has 1 entrance with 389 seats. How many seats per entrance?
389 seats.
Since there is only one entrance, all seats are accounted for under that entrance.
389 marbles are to be distributed equally among 1 container. How many marbles will be in the container?
389 marbles.
Since there is only one container, all marbles will be in that container.
