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 817, how they are used in real life, and tips to learn them quickly.
The numbers that divide 817 evenly are known as factors of 817.
A factor of 817 is a number that divides the number without a remainder.
The factors of 817 are 1, 19, 43, and 817.
Negative factors of 817: -1, -19, -43, and -817.
Prime factors of 817: 19 and 43.
Prime factorization of 817: 19 × 43.
The sum of factors of 817: 1 + 19 + 43 + 817 = 880
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 817. Identifying the numbers which are multiplied to get the number 817 is the multiplication method.
Step 1: Multiply 817 by 1, 817 × 1 = 817.
Step 2: Check for other numbers that give 817 after multiplying
19 × 43 = 817
Therefore, the positive factor pairs of 817 are: (1, 817) and (19, 43).
All these factor pairs result in 817.
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 817 by 1, 817 ÷ 1 = 817.
Step 2: Continue dividing 817 by numbers until the remainder becomes 0.
817 ÷ 1 = 817
817 ÷ 19 = 43
817 ÷ 43 = 19
Therefore, the factors of 817 are: 1, 19, 43, 817.
The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 817 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
817 ÷ 19 = 43
43 ÷ 43 = 1
The prime factors of 817 are 19 and 43.
The prime factorization of 817 is: 19 × 43.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 817 is divided by 19 to get 43.
Step 2: Now divide 43 by 43 to get 1. Here, 43 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 817 is: 19 × 43.
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 817: (1, 817) and (19, 43).
Negative factor pairs of 817: (-1, -817) and (-19, -43).
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 19 students and 817 apples. How will they divide it equally?
They will get 43 apples each.
To divide the apples equally, we need to divide the total apples by the number of students.
817/19 = 43
A rectangular field has a length of 43 meters and a total area of 817 square meters. Find the width.
19 meters.
To find the width of the field, we use the formula, Area = length × width
817 = 43 × width
To find the value of width, we need to move 43 to the left side.
817/43 = width
Width = 19.
There are 43 baskets and 817 oranges. How many oranges will be in each basket?
Each basket will have 19 oranges.
To find the oranges in each basket, divide the total oranges by the baskets.
817/43 = 19
In a class, there are 817 students, and 43 groups. How many students are there in each group?
There are 19 students in each group.
Dividing the students by the total groups, we will get the number of students in each group.
817/43 = 19
817 books need to be arranged in 19 shelves. How many books will go on each shelf?
Each shelf will have 43 books.
Divide total books by shelves.
817/19 = 43
