Using Prime Factorization: In this process, prime factors of 2520 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
2520 ÷ 2 = 1260
1260 ÷ 2 = 630
630 ÷ 2 = 315
315 ÷ 3 = 105
105 ÷ 3 = 35
35 ÷ 5 = 7
7 ÷ 7 = 1
The prime factors of 2520 are 2, 3, 5, and 7.
The prime factorization of 2520 is: 2^3 × 3^2 × 5 × 7.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 2520 is divided by 2 to get 1260.
Step 2: Now divide 1260 by 2 to get 630.
Step 3: Then divide 630 by 2 to get 315.
Step 4: Divide 315 by 3 to get 105.
Step 5: Divide 105 by 3 to get 35.
Step 6: Divide 35 by 5 to get 7.
Here, 7 is the smallest prime number, that cannot be divided anymore.
So, the prime factorization of 2520 is: 2^3 × 3^2 × 5 × 7.

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 28 friends and 2520 candies. How will they divide it equally?
They will get 90 candies each.
To divide the candies equally, we need to divide the total candies with the number of friends.
2520/28 = 90
A rectangular plot of land has a length of 35 meters and a total area of 2520 square meters. Find the width.
72 meters.
To find the width of the plot, we use the formula,
Area = length × width
2520 = 35 × width
To find the value of width, we need to shift 35 to the left side.
2520/35 = width
Width = 72.
There are 42 baskets and 2520 apples. How many apples will be in each basket?
Each basket will have 60 apples.
To find the apples in each basket, divide the total apples with the baskets.
2520/42 = 60
In a class, there are 2520 students, and 84 groups. How many students are there in each group?
There are 30 students in each group.
Dividing the students with the total groups, we will get the number of students in each group.
2520/84 = 30
2520 books need to be arranged in 56 shelves. How many books will go on each shelf?
Each of the shelves has 45 books.
Divide total books with shelves.
2520/56 = 45
