For every positive factor, there is a negative factor.
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 1440 by 1, 1440 ÷ 1 = 1440.
Step 2: Continue dividing 1440 by the numbers until the remainder becomes 0.
1440 ÷ 1 = 1440
1440 ÷ 2 = 720
1440 ÷ 3 = 40
1440 ÷ 4 = 360
1440 ÷ 5 = 288
1440 ÷ 6 = 240
1440 ÷ 8 = 180
1440 ÷ 9 = 160
1440 ÷ 10 = 144
1440 ÷ 12 = 120
1440 ÷ 15 = 96
1440 ÷ 16 = 90
1440 ÷ 18 = 80
1440 ÷ 20 = 72
1440 ÷ 24 = 60
1440 ÷ 30 = 48
1440 ÷ 32 = 45
1440 ÷ 36 = 40
Therefore, the factors of 1440 are: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 32, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 160, 180, 240, 288, 360, 480, 720, and 1440.
The factors can be found by dividing them with prime numbers. We can find the prime factors using the following methods:
Using Prime Factorization: In this process, prime factors of 1440 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.
1440 ÷ 2 = 720
720 ÷ 2 = 360
360 ÷ 2 = 180
180 ÷ 2 = 90
90 ÷ 2 = 45
45 ÷ 3 = 15
15 ÷ 3 = 5
5 ÷ 5 = 1
The prime factors of 1440 are 2, 3, and 5.
The prime factorization of 1440 is: 2^5 × 3^2 × 5.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -
Step 1: Firstly, 1440 is divided by 2 to get 720.
Step 2: Now divide 720 by 2 to get 360.
Step 3: Then divide 360 by 2 to get 180.
Step 4: Divide 180 by 2 to get 90.
Step 5: Divide 90 by 2 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 1440 is: 2^5 × 3^2 × 5.
Factor Pairs Two numbers that are multiplied to give a specific number are called 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 12 workers and 1440 bricks. How will they divide the bricks equally?
They will get 120 bricks each.
To divide the bricks equally, we need to divide the total bricks by the number of workers.
1440/12 = 120
A garden is rectangular, the length of the garden is 60 meters and the total area is 1440 square meters. Find the width?
24 meters.
To find the width of the garden, we use the formula,
Area = length × width
1440 = 60 × width
To find the value of width, divide
1440 by 60.
1440/60 = width
Width = 24.
There are 18 pallets and 1440 boxes. How many boxes will be on each pallet?
Each pallet will have 80 boxes.
To find the number of boxes on each pallet, divide the total boxes by the number of pallets.
1440/18 = 80
In a competition, there are 1440 participants, and 45 groups. How many participants are there in each group?
There are 32 participants in each group.
Dividing the participants by the total groups, we will get the number of participants in each group.
1440/45 = 32
1440 books need to be arranged in 36 boxes. How many books will go in each box?
Each of the boxes has 40 books.
Divide total books by boxes.
1440/36 = 40
