What are the Factors of 1902?
The numbers that divide 1902 evenly are known as factors of 1902.
A factor of 1902 is a number that divides the number without remainder.
The factors of 1902 are 1, 2, 3, 6, 317, 634, 951, and 1902.
Negative factors of 1902: -1, -2, -3, -6, -317, -634, -951, and -1902.
Prime factors of 1902: 2, 3, and 317.

The sum of factors of 1902: 1 + 2 + 3 + 6 + 317 + 634 + 951 + 1902 = 3816
How to Find Factors of 1902?
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 1902. Identifying the numbers which are multiplied to get the number 1902 is the multiplication method.
Step 1: Multiply 1902 by 1, 1902 × 1 = 1902.
Step 2: Check for other numbers that give 1902 after multiplying
2 × 951 = 1902
3 × 634 = 1902
6 × 317 = 1902
Therefore, the positive factor pairs of 1902 are: (1, 1902), (2, 951), (3, 634), (6, 317). All these factor pairs result in 1902.
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 1902 by 1, 1902 ÷ 1 = 1902.
Step 2: Continue dividing 1902 by the numbers until the remainder becomes 0.
1902 ÷ 1 = 1902
1902 ÷ 2 = 951
1902 ÷ 3 = 634
1902 ÷ 6 = 317
Therefore, the factors of 1902 are: 1, 2, 3, 6, 317, 634, 951, 1902.
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 1902 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1902 ÷ 2 = 951
951 ÷ 3 = 317
317 ÷ 317 = 1
The prime factors of 1902 are 2, 3, and 317.
The prime factorization of 1902 is: 2 × 3 × 317.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows
Step 1: Firstly, 1902 is divided by 2 to get 951.
Step 2: Now divide 951 by 3 to get 317.
Step 3: Here, 317 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1902 is: 2 × 3 × 317.
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 1902: (1, 1902), (2, 951), (3, 634), and (6, 317).
Negative factor pairs of 1902: (-1, -1902), (-2, -951), (-3, -634), and (-6, -317).
Common Mistakes and How to Avoid Them in Factors of 1902
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 1902, 1 and 1902 is also a factor.
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 1902 consist of -1, -2, -3, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions also as factors. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor, because 1902/1.5 = 1268, 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 1902 are prime numbers. For example, 2, 3, and 317 are the prime factors of 1902, but it has other factors like 6, 951.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 1902 as 2 × 3 × 317 and missing all the key factors.
Factors of 1902 Examples
Problem 1
There are 18 employees and 1902 promotional items. How will they distribute them equally?
They will get 105 promotional items each.
Explanation
To distribute the items equally, we need to divide the total items by the number of employees.
1902/18 = 105
Problem 2
A garden is rectangular, the length of the garden is 6 meters and the total area is 1902 square meters. Find the width?
317 meters.
Explanation
To find the width of the garden, we use the formula,
Area = length × width
1902 = 6 × width
To find the value of width, we need to shift 6 to the left side.
1902/6 = width
Width = 317.
Problem 3
There are 951 balls and 951 boxes. How many balls will be in each box?
Each box will have 1 ball.
Explanation
To find the balls in each box, divide the total balls by the boxes.
951/951 = 1
Problem 4
In a conference, there are 951 participants, and 3 groups. How many participants are there in each group?
There are 317 participants in each group.
Explanation
Dividing the participants by the total groups, we will get the number of participants in each group.
951/3 = 317
Problem 5
1902 photographs need to be arranged in 6 albums. How many photographs will go in each album?
Each of the albums has 317 photographs.
Explanation
Divide total photographs by albums.
1902/6 = 317
