What are the Factors of 1881?
The numbers that divide 1881 evenly are known as factors of 1881.
A factor of 1881 is a number that divides the number without remainder.
The factors of 1881 are 1, 3, 19, 57, 33, 63, 209, 627, and 1881.
Negative factors of 1881: -1, -3, -19, -57, -33, -63, -209, -627, and -1881.
Prime factors of 1881: 3 and 19.
Prime factorization of 1881: 3 × 19 × 33.
The sum of factors of 1881: 1 + 3 + 19 + 57 + 33 + 63 + 209 + 627 + 1881 = 2892
How to Find Factors of 1881?
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 1881. Identifying the numbers which are multiplied to get the number 1881 is the multiplication method.
Step 1: Multiply 1881 by 1, 1881 × 1 = 1881.
Step 2: Check for other numbers that give 1881 after multiplying
3 × 627 = 1881
19 × 99 = 1881
Therefore, the positive factor pairs of 1881 are: (1, 1881), (3, 627), (19, 99). All these factor pairs result in 1881. 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 the simple division method
Step 1: Divide 1881 by 1, 1881 ÷ 1 = 1881.
Step 2: Continue dividing 1881 by the numbers until the remainder becomes 0.
1881 ÷ 1 = 1881
1881 ÷ 3 = 627
1881 ÷ 19 = 99
Therefore, the factors of 1881 are: 1, 3, 19, 57, 33, 63, 209, 627, 1881.
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 1881 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1881 ÷ 3 = 627
627 ÷ 3 = 209
209 ÷ 19 = 11
11 ÷ 11 = 1
The prime factors of 1881 are 3 and 19.
The prime factorization of 1881 is: 3 × 19 × 33.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1881 is divided by 3 to get 627.
Step 2: Now divide 627 by 3 to get 209.
Step 3: Then divide 209 by 19 to get 11. Here, 11 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 1881 is: 3 × 19 × 33.
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 1881: (1, 1881), (3, 627), (19, 99).
Negative factor pairs of 1881: (-1, -1881), (-3, -627), (-19, -99).
Common Mistakes and How to Avoid Them in Factors of 1881
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 1881, 1 and 1881 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 1881 consist of -1, -3, -19, etc.
Mistake 3
Including Fractions
Children might sometimes add fractions as factors. Only whole numbers can be factors.
For example, thinking 1.5 is a factor, because 1881/1.5 does not result in 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 1881 are prime numbers. For example, 3 and 19 are the prime factors of 1881, but it has other factors like 57, 99.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1881 as 3 × 19 × 33 and missing all the key factors.
Factors of 1881 Examples
Problem 1
There are 3 siblings and 1881 candies. How will they divide them equally?
They will get 627 candies each.
Explanation
To divide the candies equally, we need to divide the total candies by the number of siblings.
1881/3 = 627
Problem 2
A wall is rectangular, the length of the wall is 19 meters and the total area is 1881 square meters. Find the width.
99 meters.
Explanation
To find the width of the wall, we use the formula, Area = length × width
1881 = 19 × width
To find the value of width, we need to shift 19 to the left side.
1881/19 = width
Width = 99.
Problem 3
There are 57 rolls of fabric and 1881 meters of fabric. How many meters will be in each roll?
Each roll will have 33 meters.
Explanation
To find the meters in each roll, divide the total meters by the rolls.
1881/57 = 33
Problem 4
In a conference, there are 1881 participants, and 19 groups. How many participants are there in each group?
There are 99 participants in each group.
Explanation
Dividing the participants by the total groups, we will get the number of participants in each group.
1881/19 = 99
Problem 5
1881 books need to be arranged in 3 shelves. How many books will go on each shelf?
Each of the shelves has 627 books.
Explanation
Divide total books by shelves. 1881/3 = 627
