What are the Factors of 1830?
The numbers that divide 1830 evenly are known as factors of 1830.
A factor of 1830 is a number that divides the number without remainder.
The factors of 1830 are 1, 2, 3, 5, 6, 10, 15, 30, 61, 122, 183, 305, 366, 610, 915, and 1830.

The sum of factors of 1830: 1 + 2 + 3 + 5 + 6 + 10 + 15 + 30 + 61 + 122 + 183 + 305 + 366 + 610 + 915 + 1830 = 4464
How to Find Factors of 1830?
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 1830. Identifying the numbers which are multiplied to get the number 1830 is the multiplication method.
Step 1: Multiply 1830 by 1, 1830 × 1 = 1830.
Step 2: Check for other numbers that give 1830 after multiplying
2 × 915 = 1830
3 × 610 = 1830
5 × 366 = 1830
6 × 305 = 1830
Therefore, the positive factor pairs of 1830 are: (1, 1830), (2, 915), (3, 610), (5, 366), (6, 305).
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 1830 by 1, 1830 ÷ 1 = 1830.
Step 2: Continue dividing 1830 by the numbers until the remainder becomes 0.
1830 ÷ 1 = 1830
1830 ÷ 2 = 915
1830 ÷ 3 = 610
1830 ÷ 5 = 366
1830 ÷ 6 = 305
Therefore, the factors of 1830 are: 1, 2, 3, 5, 6, 10, 15, 30, 61, 122, 183, 305, 366, 610, 915, 1830.
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 1830 divide the number to break it down into the multiplication form of prime factors till the remainder becomes 1.
1830 ÷ 2 = 915
915 ÷ 3 = 305
305 ÷ 5 = 61
61 ÷ 61 = 1
The prime factors of 1830 are 2, 3, 5, and 61.
The prime factorization of 1830 is: 2 × 3 × 5 × 61.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1830 is divided by 2 to get 915.
Step 2: Now divide 915 by 3 to get 305.
Step 3: Then divide 305 by 5 to get 61.
Step 4: Here, 61 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 1830 is: 2 × 3 × 5 × 61.
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 1830: (1, 1830), (2, 915), (3, 610), (5, 366), (6, 305).
Negative factor pairs of 1830: (-1, -1830), (-2, -915), (-3, -610), (-5, -366), (-6, -305).
Common Mistakes and How to Avoid Them in Factors of 1830
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 1830, 1 and 1830 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 1830 consist of -1, -2, -3, 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 1830/1.5 = 1220, 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 1830 are prime numbers.
For example, 2, 3, 5, and 61 are the prime factors of 1830, but it has other factors like 10, 15.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1830 as 2 × 3 × 5 × 61 and missing all the key factors.
Factors of 1830 Examples
Problem 1
A group of 6 musicians needs to equally divide 1830 sheets of music. How many sheets will each musician get?
Each musician will get 305 sheets.
Explanation
To divide the sheets equally, we need to divide the total sheets by the number of musicians.
1830/6 = 305
Problem 2
A rectangular garden has a length of 61 meters and a total area of 1830 square meters. Find the width.
30 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
1830 = 61 × width
To find the value of width, we need to divide the area by the length.
1830/61 = width
Width = 30.
Problem 3
There are 915 cupcakes to be distributed among 183 children. How many cupcakes will each child receive?
Each child will receive 5 cupcakes.
Explanation
To find the cupcakes each child will receive, divide the total cupcakes by the number of children.
915/183 = 5
Problem 4
A theater has 305 seats and 5 rows. How many seats are there in each row?
There are 61 seats in each row.
Explanation
Dividing the total number of seats by the total rows, we will get the number of seats in each row.
305/5 = 61
Problem 5
1830 apples need to be packed into boxes, with each box holding 30 apples. How many boxes are needed?
61 boxes are needed.
Explanation
Divide the total number of apples by the apples per box.
1830/30 = 61
