Factors of 218
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 218, how they are used in real life, and tips to learn them quickly.
What are the Factors of 218?
The numbers that divide 218 evenly are known as factors of 218.
A factor of 218 is a number that divides the number without remainder.
The factors of 218 are 1, 2, 109, and 218.
Negative factors of 218: -1, -2, -109, and -218.
Prime factors of 218: 2 and 109.
Prime factorization of 218: 2 × 109.
The sum of factors of 218: 1 + 2 + 109 + 218 = 330
How to Find Factors of 218?
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 multiply to give 218. Identifying the numbers that are multiplied to get the number 218 is the multiplication method.
Step 1: Multiply 218 by 1, 218 × 1 = 218.
Step 2: Check for other numbers that give 218 after multiplying.
2 × 109 = 218
Therefore, the positive factor pairs of 218 are: (1, 218) and (2, 109).
All these factor pairs result in 218.
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 218 by 1,
218 ÷ 1 = 218.
Step 2: Continue dividing 218 by the numbers until the remainder becomes 0.
218 ÷ 1 = 218
218 ÷ 2 = 109
Therefore, the factors of 218 are: 1, 2, 109, and 218.
Prime Factors and Prime Factorization
The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:
- Using prime factorization
- Using a factor tree
Using Prime Factorization: In this process, prime factors of 218 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
218 ÷ 2 = 109
109 is a prime number, so the division stops here.
The prime factors of 218 are 2 and 109.
The prime factorization of 218 is: 2 × 109.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows:
Step 1: Firstly, 218 is divided by 2 to get 109.
Here, 109 is a prime number, that cannot be divided anymore.
So, the prime factorization of 218 is: 2 × 109.
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 218: (1, 218) and (2, 109).
Negative factor pairs of 218: (-1, -218) and (-2, -109).
Common Mistakes and How to Avoid Them in Factors of 218
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and 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 factors for every number. Always remember to include 1 and the number itself.
For example, in factors of 218, 1 and 218 are also factors.
Mistake 2
Missing Negative Factors
We often mention only positive factors. There are also negative factors, always check whether you have mentioned negative factors.
For example, the factors of 218 include -1, -2, -109, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as factors. Only whole numbers can be factors.
For example, thinking 1.5 is a factor because 218/1.5 ≈ 145.333, which is not a whole number.
Mistake 4
Confusing Factors With Prime Numbers
Remember that factors can be any whole numbers, not only primes.
For example, thinking all the factors of 218 are prime numbers. For instance, 2 and 109 are the prime factors of 218, but it has other factors like 1 and 218.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing the wrong factors.
For example, Not breaking 218 as 2 × 109 and missing key factors.
Factors of 218 Examples
Problem 1
There are 2 containers and 218 apples. How will they be divided equally?
Each container will get 109 apples.
Explanation
To divide the apples equally, we need to divide the total apples by the number of containers.
218/2 = 109
Problem 2
A rectangular garden has a length of 2 meters and a total area of 218 square meters. Find the width.
109 meters.
Explanation
To find the width of the garden, we use the formula, Area = length × width
218 = 2 × width
To find the value of width, we need to shift 2 to the left side.
218/2 = width
Width = 109.
Problem 3
There are 109 students and 218 seats in an auditorium. How many students will be seated in each row if there are 2 rows?
Each row will have 109 students.
Explanation
To find the students in each row, divide the total students by the number of rows.
218/2 = 109
Problem 4
In a library, there are 218 books, and 109 shelves. How many books are there in each shelf?
There are 2 books in each shelf.
Explanation
Dividing the books by the total shelves, we will get the number of books in each shelf.
218/109 = 2
Problem 5
218 marbles need to be arranged in 109 bags. How many marbles will go in each bag?
Each bag will have 2 marbles.
Explanation
Divide the total marbles by the bags.
218/109 = 2
