What are Factors of 6400?
Factors of 6400 are pairs of those numbers whose products result in 6400. These factors are either prime numbers or composite numbers.
How to Find the Factors of 6400?
To find the factors of 6400, we will have to find the list of numbers that would divide 6400 without leaving any remainder.
- 6400/10 = 640; therefore, 10 is a factor of 6400 and 640 is also a factor of 6400.
- 6400/2 = 3200; therefore, 2 is a factor of 6400 and 3200 is also a factor of 6400.

Factors of 6400 by Prime Factorization
- 6400 ÷ 2 = 3200
- 3200 ÷ 2 = 1600
- 1600 ÷ 2 = 800
- 800 ÷ 2 = 400
- 400 ÷ 2 = 200
- 200 ÷ 2 = 100
- 100 ÷ 2 = 50
- 50 ÷ 2 = 25
Further dividing 25 by 2 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 6400 can be written as 28 × 52 where 2, 5 are prime.
