Step 1: Multiply 3240 by 1, 3240 × 1 = 3240.
Step 2: Check for other numbers that give 3240 after multiplying
2 × 1620 = 3240
3 × 1080 = 3240
4 × 810 = 3240
5 × 648 = 3240
6 × 540 = 3240
8 × 405 = 3240

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 3240 by 1, 3240 ÷ 1 = 3240.
Step 2: Continue dividing 3240 by the numbers until the remainder becomes 0.
3240 ÷ 1 = 3240
3240 ÷ 2 = 1620
3240 ÷ 3 = 1080
3240 ÷ 4 = 810
3240 ÷ 5 = 648

Prime Factors and Prime Factorization
The factors can be found by dividing 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 3240 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
3240 ÷ 2 = 1620
1620 ÷ 2 = 810
810 ÷ 2 = 405
405 ÷ 3 = 135
135 ÷ 3 = 45
45 ÷ 3 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1
The prime factors of 3240 are 2, 3, and 5.
The prime factorization of 3240 is: 23 × 34 × 5.
Factor Tree
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 3240 is divided by 2 to get 1620.
Step 2: Now divide 1620 by 2 to get 810.
Step 3: Then divide 810 by 2 to get 405.
Step 4: Divide 405 by 3 to get 135.
Step 5: Divide 135 by 3 to get 45.
Step 6: Divide 45 by 3 to get 15.
Step 7: Divide 15 by 3 to get 5. Here, 5 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 3240 is: 23 × 34 × 5.
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 3240: (1, 3240), (2, 1620), (3, 1080), (4, 810), (5, 648), (6, 540), (8, 405), (9, 360), (10, 324), (12, 270), (15, 216), (18, 180), (20, 162), (24, 135), (27, 120), (30, 108), (36, 90), (40, 81), (45, 72), and (54, 60).

Common Mistakes and How to Avoid Them in Factors of 3240
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 3240, 1 and 3240 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 3240 consist of -1, -2, -3, etc.
Mistake 3
Including the Fraction
Children might sometimes add fractions as a factor. Only whole numbers can be a factor.
For example, thinking 1.5 as a factor, because 3240/1.5 ≠ 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 3240 are prime numbers.
For example, 2, 3, and 5 are the prime factors of 3240, but it has other factors like 4, 10.
Mistake 5
Mistake in Factorization
Children might skip the steps in factorization and end up writing wrong factors.
For example, not breaking 3240 as 2^3 × 3^4 × 5 and missing all the key factors.
Factors of 3240 Examples
Problem 1
There are 18 friends and 3240 candies. How will they divide it equally?
They will get 180 candies each.
Explanation
To divide the candies equally, we need to divide the total candies by the number of friends.
3240/18 = 180
Problem 2
A field is rectangular, the length of the field is 108 meters and the total area is 3240 square meters. Find the width.
30 meters.
Explanation
To find the width of the field, we use the formula,
Area = length × width
3240 = 108 × width
To find the value of width, we need to shift 108 to the left side.
3240/108 = width
Width = 30.
