What are Factors of 2800?
Factors of 2800 are pairs of those numbers whose products result in 2800. These factors are either prime numbers or composite numbers.
How to Find the Factors of 2800?
To find the factors of 2800, we will have to find the list of numbers that would divide 2800 without leaving any remainder.
- 2800/400 = 7; therefore, 400 is a factor of 2800 and 7 is also a factor of 2800.
- 2800/4 = 700; therefore, 4 is a factor of 2800 and 700 is also a factor of 2800.

Factors of 2800 by Prime Factorization
- 2800 ÷ 2 = 1400
- 1400 ÷ 2 = 700
- 700 ÷ 2 = 350
- 350 ÷ 2 = 175
Further dividing 175 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 175 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 2800 can be written as 24 × 52 × 71 where 2, 5, 7 are prime.

Example 1: How many factors are there for 2800?
Solution:
The factors of 2800 are too many, therefore if we can find the prime factorization of 2800, then the total number of factors can be calculated using the formula shown below.
