The factors can be found by dividing with prime numbers. We can find the prime factors using the following methods:
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.
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.

Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
There are 18 friends and 3240 candies. How will they divide it equally?
They will get 180 candies each.
To divide the candies equally, we need to divide the total candies by the number of friends.
3240/18 = 180
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.
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.
There are 45 bags and 3240 marbles. How many marbles will be in each bag?
Each bag will have 72 marbles.
To find the marbles in each bag, divide the total marbles by the bags.
3240/45 = 72
In a class, there are 3240 students, and 90 groups. How many students are there in each group?
There are 36 students in each group.
Dividing the students by the total groups, we will get the number of students in each group.
3240/90 = 36
3240 books need to be arranged in 135 shelves. How many books will go on each shelf?
Each of the shelves has 24 books.
Divide total books by shelves.
3240/135 = 24
