Factors of 242
Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 242, how they are used in real life, and the tips to learn them quickly.
What are the Factors of 242?
The numbers that divide 242 evenly are known as factors of 242.
A factor of 242 is a number that divides the number without remainder.
The factors of 242 are 1, 2, 11, 22, 121, and 242.
Negative factors of 242: -1, -2, -11, -22, -121, and -242.
Prime factors of 242: 2 and 11.
Prime factorization of 242: 2 × 11².
The sum of factors of 242: 1 + 2 + 11 + 22 + 121 + 242 = 399
How to Find Factors of 242?
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 242. Identifying the numbers which are multiplied to get the number 242 is the multiplication method.
Step 1: Multiply 242 by 1, 242 × 1 = 242.
Step 2: Check for other numbers that give 242 after multiplying
2 × 121 = 242
11 × 22 = 242
Therefore, the positive factor pairs of 242 are: (1, 242), (2, 121), (11, 22).
All these factor pairs result in 242.
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 242 by 1, 242 ÷ 1 = 242.
Step 2: Continue dividing 242 by the numbers until the remainder becomes 0.
242 ÷ 1 = 242
242 ÷ 2 = 121
242 ÷ 11 = 22
Therefore, the factors of 242 are: 1, 2, 11, 22, 121, 242.
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 factor tree
Using Prime Factorization: In this process, prime factors of 242 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
242 ÷ 2 = 121
121 ÷ 11 = 11
11 ÷ 11 = 1
The prime factors of 242 are 2 and 11.
The prime factorization of 242 is: 2 × 11².
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 242 is divided by 2 to get 121.
Step 2: Now divide 121 by 11 to get 11.
Step 3: Divide 11 by 11 to get 1.
Here, 11 is a prime number, and it cannot be divided anymore.
So, the prime factorization of 242 is: 2 × 11².
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 242: (1, 242), (2, 121), (11, 22).
Negative factor pairs of 242: (-1, -242), (-2, -121), (-11, -22).
Common Mistakes and How to Avoid Them in Factors of 242
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 242, 1 and 242 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 242 consist of -1, -2, -11, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as a factor. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor, because 242/1.5 = 161.333, 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 242 are prime numbers. For example, 2 and 11 are the prime factors of 242, but it has other factors like 22, 121.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 242 as 2 × 11² and missing all the key factors.
Factors of 242 Examples
Problem 1
There are 11 friends and 242 candies. How will they divide it equally?
They will get 22 candies each.
Explanation
To divide the candies equally, we need to divide the total candies with the number of friends.
242/11 = 22
Problem 2
A field is rectangular, the length of the field is 11 meters and the total area is 242 square meters. Find the width?
22 meters.
Explanation
To find the width of the field, we use the formula, Area = length × width
242 = 11 × width
To find the value of width, we need to shift 11 to the left side.
242/11 = width
Width = 22.
Problem 3
There are 2 boxes and 242 marbles. How many marbles will be in each box?
Each box will have 121 marbles.
Explanation
To find the marbles in each box, divide the total marbles with the boxes.
242/2 = 121
Problem 4
In a class, there are 242 students, and 11 groups. How many students are there in each group?
There are 22 students in each group.
Explanation
Dividing the students with the total groups, we will get the number of students in each group.
242/11 = 22
Problem 5
242 books need to be arranged in 22 shelves. How many books will go on each shelf?
Each of the shelves has 11 books.
Explanation
Divide total books with shelves.
242/22 = 11
