What are Factors of 2005?
Factors of 2005 are pairs of those numbers whose products result in 2005. These factors are either prime numbers or composite numbers.
How to Find the Factors of 2005?
To find the factors of 2005, we will have to find the list of numbers that would divide 2005 without leaving any remainder.
- 2005/5 = 401; therefore, 5 is a factor of 2005 and 401 is also a factor of 2005.
- 2005/1 = 2005; therefore, 1 is a factor of 2005 and 2005 is also a factor of 2005.

Factors of 2005 by Prime Factorization
- 2005 ÷ 5 = 401
Further dividing 401 by 5 gives a non-zero remainder. So we stop the process and continue dividing the number 401 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 2005 can be written as 51 × 4011 where 5, 401 are prime.
Factors of 2005 in Pairs
Pair factors of 2005 are the pairs of numbers that when multiplied give the product 2005. The factors of 2005 in pairs are:
- 1 × 2005 = (1, 2005)
- 5 × 401 = (5, 401)
Negative pair factors of 2005 are:
- -1 × -2005 = (-1, -2005)
- -5 × -401 = (-5, -401)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
