Factors of 1819
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 1819, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1819?
The numbers that divide 1819 evenly are known as factors of 1819.
A factor of 1819 is a number that divides the number without a remainder.
The factors of 1819 are 1, 7, 13, 19, 91, 133, 247, and 1819.
Negative factors of 1819: -1, -7, -13, -19, -91, -133, -247, and -1819.
Prime factors of 1819: 7, 13, and 19.
Prime factorization of 1819: 7 × 13 × 19.
The sum of factors of 1819: 1 + 7 + 13 + 19 + 91 + 133 + 247 + 1819 = 2330
How to Find Factors of 1819?
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 1819. Identifying the numbers which are multiplied to get the number 1819 is the multiplication method.
Step 1: Multiply 1819 by 1, 1819 × 1 = 1819.
Step 2: Check for other numbers that give 1819 after multiplying
7 × 259 = 1819
13 × 139 = 1819
19 × 95 = 1819
Therefore, the positive factor pairs of 1819 are: (1, 1819), (7, 259), (13, 139), (19, 95).
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 1819 by 1, 1819 ÷ 1 = 1819.
Step 2: Continue dividing 1819 by the numbers until the remainder becomes 0.
1819 ÷ 1 = 1819
1819 ÷ 7 = 259
1819 ÷ 13 = 139
1819 ÷ 19 = 95
Therefore, the factors of 1819 are: 1, 7, 13, 19, 91, 133, 247, and 1819.
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 1819 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1819 ÷ 7 = 259
259 ÷ 13 = 19
19 ÷ 19 = 1
The prime factors of 1819 are 7, 13, and 19.
The prime factorization of 1819 is: 7 × 13 × 19.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1819 is divided by 7 to get 259.
Step 2: Now divide 259 by 13 to get 19.
Step 3: Divide 19 by 19 to get 1.
Here, 19 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1819 is: 7 × 13 × 19.
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 1819: (1, 1819), (7, 259), (13, 139), and (19, 95).
Negative factor pairs of 1819: (-1, -1819), (-7, -259), (-13, -139), and (-19, -95).
Common Mistakes and How to Avoid Them in Factors of 1819
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 word. Always remember to include 1 and the number itself.
For example, in factors of 1819, 1 and 1819 are also factors.
Factors of 1819 Examples
Problem 1
There are 13 students and 1819 candies. How will they divide it equally?
They will get 139 candies each.
Explanation
To divide the candies equally, we need to divide the total candies by the number of students.
1819/13 = 139
Problem 2
A garden is rectangular, the length of the garden is 19 meters and the total area is 1819 square meters. Find the width?
95 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
1819 = 19 × width
To find the value of width, we need to shift 19 to the left side.
1819/19 = width
Width = 95.
Problem 3
There are 7 shelves and 1819 books. How many books will be on each shelf?
Each shelf will have 259 books.
Explanation
To find the books on each shelf, divide the total books by the number of shelves.
1819/7 = 259
Problem 4
In a university, there are 1819 students, and 19 groups. How many students are there in each group?
There are 95 students in each group.
Explanation
Dividing the students by the total groups, we will get the number of students in each group.
1819/19 = 95
Problem 5
1819 apples need to be packed in 91 boxes. How many apples will go in each box?
Each of the boxes has 20 apples.
Explanation
Divide total apples by boxes.
1819/91 = 20
