Factors of 818
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 818, how they are used in real life, and tips to learn them quickly.
What are the Factors of 818?
The numbers that divide 818 evenly are known as factors of 818.
A factor of 818 is a number that divides the number without remainder.
The factors of 818 are 1, 2, 409, and 818.
Negative factors of 818: -1, -2, -409, and -818.
Prime factors of 818: 2 and 409.
Prime factorization of 818: 2 × 409.
The sum of factors of 818: 1 + 2 + 409 + 818 = 1230
How to Find Factors of 818?
Factors can be found using different methods. Mentioned below are some commonly used methods:
- Finding factors using multiplication
- Finding factors using the 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 818. Identifying the numbers which are multiplied to get the number 818 is the multiplication method.
Step 1: Multiply 818 by 1, 818 × 1 = 818. Step 2: Check for other numbers that give 818 after multiplying
2 × 409 = 818
Therefore, the positive factor pairs of 818 are: (1, 818) and (2, 409).
All these factor pairs result in 818.
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 818 by 1, 818 ÷ 1 = 818.
Step 2: Continue dividing 818 by the numbers until the remainder becomes 0.
818 ÷ 1 = 818
818 ÷ 2 = 409
818 ÷ 409 = 2
Therefore, the factors of 818 are: 1, 2, 409, and 818.
Prime Factors and Prime Factorization
The factors can be found by dividing it by 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 818 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
818 ÷ 2 = 409
409 ÷ 409 = 1
The prime factors of 818 are 2 and 409.
The prime factorization of 818 is: 2 × 409.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 818 is divided by 2 to get 409.
Step 2: 409 is a prime number and cannot be divided further. So, the prime factorization of 818 is: 2 × 409.
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 818: (1, 818) and (2, 409).
Negative factor pairs of 818: (-1, -818) and (-2, -409).
Common Mistakes and How to Avoid Them in Factors of 818
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 whole number. Always remember to include 1 and the number itself.
For example, in factors of 818, 1 and 818 are also factors.
Mistake 2
Missing Negative Factors
We have used only to mention positive factors every time. There are also negative factors, always check whether you have mentioned negative factors.
For example, the factors of 818 consist of -1, -2, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as factors. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor because 818/1.5 = 545.333, and it is not a whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole numbers, not only just primes.
For example, thinking all the factors of 818 are prime numbers.
For example, 2 and 409 are the prime factors of 818, but it has other factors like 1, 818.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing the wrong factors.
For example, not breaking 818 as 2 × 409 and missing all the key factors.
Factors of 818 Examples
Problem 1
There are 818 apples and 2 baskets. How will they divide it equally?
They will get 409 apples each.
Explanation
To divide the apples equally, we need to divide the total apples by the number of baskets.
818/2 = 409
Problem 2
A rectangular painting has a length of 2 meters and a total area of 818 square meters. Find the width?
409 meters.
Explanation
To find the width of the painting, we use the formula,
Area = length × width
818 = 2 × width
To find the value of width, we need to shift 2 to the left side.
818/2 = width
Width = 409.
Problem 3
There are 409 books and 2 shelves. How many books will be in each shelf?
Each shelf will have 204.5 books.
Explanation
To find the books in each shelf, divide the total books by the number of shelves.
409/2 = 204.5
Problem 4
A class has 818 students, and there are 409 groups. How many students are there in each group?
There are 2 students in each group.
Explanation
Dividing the students by the total groups, we will get the number of students in each group.
818/409 = 2
Problem 5
818 candies need to be arranged in 1 box. How many candies will go in each box?
All 818 candies will go in the box.
Explanation
Divide total candies by the number of boxes.
818/1 = 818
