Factors of 451
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 451, how they are used in real life, and tips to learn them quickly.
What are the Factors of 451?
The numbers that divide 451 evenly are known as factors of 451.
A factor of 451 is a number that divides the number without remainder.
The factors of 451 are 1, 11, 41, and 451.
Negative factors of 451: -1, -11, -41, and -451.
Prime factors of 451: 11 and 41.
Prime factorization of 451: 11 × 41.
The sum of factors of 451: 1 + 11 + 41 + 451 = 504
How to Find Factors of 451?
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 451. Identifying the numbers which are multiplied to get the number 451 is the multiplication method.
Step 1: Multiply 451 by 1, 451 × 1 = 451.
Step 2: Check for other numbers that give 451 after multiplying 11 × 41 = 451
Therefore, the positive factor pairs of 451 are: (1, 451) and (11, 41).
For every positive factor, there is a negative factor.
Finding Factors Using Division Method
Dividing the given numbers with 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 451 by 1, 451 ÷ 1 = 451.
Step 2: Continue dividing 451 by the numbers until the remainder becomes 0.
451 ÷ 1 = 451
451 ÷ 11 = 41
Therefore, the factors of 451 are: 1, 11, 41, 451.
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 451 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.
451 ÷ 11 = 41
41 ÷ 41 = 1
The prime factors of 451 are 11 and 41.
The prime factorization of 451 is: 11 × 41.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 451 is divided by 11 to get 41.
Step 2: Now divide 41 by 41 to get 1. Here, both 11 and 41 are prime numbers and cannot be divided anymore.
So, the prime factorization of 451 is: 11 × 41.
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 451: (1, 451) and (11, 41).
Negative factor pairs of 451: (-1, -451) and (-11, -41).
Common Mistakes and How to Avoid Them in Factors of 451
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 factors for every number. Always remember to include 1 and the number itself.
For example, in factors of 451, 1 and 451 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 451 consist of -1, -11, -41, 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 as a factor because 451/1.5 ≈ 300.67, 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 451 are prime numbers.
For example, 11 and 41 are the prime factors of 451, but it has other factors like 1 and 451.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 451 as 11 × 41 and missing all the key factors.
Factors of 451 Examples
Problem 1
There are 11 friends and 451 pages to read. How can they share the pages equally?
They will each read 41 pages.
Explanation
To divide the pages equally, we need to divide the total pages by the number of friends.
451/11 = 41
Problem 2
A rectangular garden has a length of 41 meters and the total area is 451 square meters. Find the width.
11 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
451 = 41 × width
To find the value of width, we need to shift 41 to the left side.
451/41 = width
Width = 11.
Problem 3
There are 41 baskets and 451 apples. How many apples will be in each basket?
Each basket will have 11 apples.
Explanation
To find the apples in each basket, divide the total apples by the baskets.
451/41 = 11
Problem 4
In a conference, there are 451 participants, and 11 rooms. How many participants are there in each room?
There are 41 participants in each room.
Explanation
Dividing the participants by the total rooms, we will get the number of participants in each room.
451/11 = 41
Problem 5
451 books need to be arranged in 41 shelves. How many books will go on each shelf?
Each of the shelves has 11 books.
Explanation
Divide total books by shelves.
451/41 = 11
