What are Factors of 2025?
Factors of 2025 are pairs of those numbers whose products result in 2025. These factors are either prime numbers or composite numbers.
How to Find the Factors of 2025?
To find the factors of 2025, we will have to find the list of numbers that would divide 2025 without leaving any remainder.
- 2025/2025 = 1; therefore, 2025 is a factor of 2025.
- 2025/3 = 675; therefore, 3 is a factor of 2025.

Factors of 2025 by Prime Factorization
- 2025 ÷ 3 = 675
- 675 ÷ 3 = 225
- 225 ÷ 3 = 75
- 75 ÷ 3 = 25
Further dividing 25 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 25 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 2025 can be written as 34 × 52 where 3, 5 are prime.

Example 1: How many factors are there for 2025?
Solution:
The factors of 2025 are too many, therefore if we can find the prime factorization of 2025, 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 2025 = 34 × 52
Therefore, the total number of factors are (4 + 1) × (2 + 1) = 5 × 3 = 15 -
