What are Factors of 1080?
Factors of 1080 are pairs of those numbers whose products result in 1080. These factors are either prime numbers or composite numbers.
How to Find the Factors of 1080?
To find the factors of 1080, we will have to find the list of numbers that would divide 1080 without leaving any remainder.
- 1080/9 = 120; therefore, 9 is a factor of 1080 and 120 is also a factor of 1080.
- 1080/360 = 3; therefore, 360 is a factor of 1080 and 3 is also a factor of 1080.

Factors of 1080 by Prime Factorization
- 1080 ÷ 2 = 540
- 540 ÷ 2 = 270
- 270 ÷ 2 = 135
Further dividing 135 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 135 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.
So, the prime factorization of 1080 can be written as 23 × 33 × 51 where 2, 3, 5 are prime.

Example 1: How many factors are there for 1080?
Solution:
The factors of 1080 are too many, therefore if we can find the prime factorization of 1080, then the total number of factors can be calculated using the formula shown below.
If the prime factorization of the number is ax × by × cz where a, b, c are prime, then the total number of factors can be given by (x + 1)(y + 1)(z + 1).
Prime Factorization of 1080 = 23 × 33 × 51
Therefore, the total number of factors are (3 + 1) × (3 + 1) × (1 + 1) = 4 × 4 × 2 = 32 -
