Factors of 1211
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 1211, how they are used in real life, and tips to learn them quickly.
What are the Factors of 1211?
The numbers that divide 1211 evenly are known as factors of 1211.
A factor of 1211 is a number that divides the number without remainder.
The factors of 1211 are 1, 11, 101, and 1211.
Negative factors of 1211: -1, -11, -101, and -1211.
Prime factors of 1211: 11 and 101. Prime factorization of 1211: 11 × 101.
The sum of factors of 1211: 1 + 11 + 101 + 1211 = 1324
How to Find Factors of 1211?
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 1211. Identifying the numbers which are multiplied to get the number 1211 is the multiplication method.
Step 1: Multiply 1211 by 1, 1211 × 1 = 1211.
Step 2: Check for other numbers that give 1211 after multiplying 11 × 101 = 1211
Therefore, the positive factor pairs of 1211 are: (1, 1211) and (11, 101).
All these factor pairs result in 1211. 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 the simple division method -
Step 1: Divide 1211 by 1, 1211 ÷ 1 = 1211.
Step 2: Continue dividing 1211 by the numbers until the remainder becomes 0.
1211 ÷ 1 = 1211
1211 ÷ 11 = 101
1211 ÷ 101 = 11
1211 ÷ 1211 = 1
Therefore, the factors of 1211 are: 1, 11, 101, 1211.
Prime Factors and Prime Factorization
The factors can be found by dividing it with a prime number. 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 1211 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1211 ÷ 11 = 101
101 ÷ 101 = 1
The prime factors of 1211 are 11 and 101.
The prime factorization of 1211 is: 11 × 101.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1211 is divided by 11 to get 101.
Step 2: Now divide 101 by 101 to get 1. Here, both 11 and 101 are prime numbers that cannot be divided anymore. So, the prime factorization of 1211 is: 11 × 101.
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 1211: (1, 1211) and (11, 101).
Negative factor pairs of 1211: (-1, -1211) and (-11, -101).
Common Mistakes and How to Avoid Them in Factors of 1211
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 number. Always remember to include 1 and the number itself.
For example, in factors of 1211, 1 and 1211 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 1211 consist of -1, -11, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions as factors. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor, because 1211/1.5 = 807.333, 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 1211 are prime numbers. For example, 11 and 101 are the prime factors of 1211, but it has other factors like 1 and 1211.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1211 as 11 × 101 and missing all the key factors.
Factors of 1211 Examples
Problem 1
There are 11 teams and 1211 fans. How will they distribute the fans equally among the teams?
Each team will have 101 fans.
Explanation
To distribute the fans equally, we need to divide the total fans by the number of teams.
1211 ÷ 11 = 101
Problem 2
A garden is rectangular, the width of the garden is 11 meters and the total area is 1211 square meters. Find the length.
101 meters.
Explanation
To find the length of the garden, we use the formula, Area = length × width
1211 = 11 × length
To find the value of length, we need to shift 11 to the left side.
1211 ÷ 11 = length
Length = 101.
Problem 3
There are 101 gift boxes and 1211 candies. How many candies will be in each box?
Each box will have 11 candies.
Explanation
To find the candies in each box, divide the total candies by the number of boxes.
1211 ÷ 101 = 11
Problem 4
In a school, there are 1211 students, and 11 buses. How many students are there in each bus?
There are 101 students in each bus.
Explanation
Dividing the students by the total number of buses, we will get the number of students in each bus.
1211 ÷ 11 = 101
Problem 5
1211 chairs need to be arranged in 11 rows. How many chairs will go in each row?
Each of the rows will have 101 chairs.
Explanation
Divide total chairs by the number of rows.
1211 ÷ 11 = 101
