What are Factors of 205?
Factors of 205 are pairs of those numbers whose products result in 205. These factors are either prime numbers or composite numbers.
How to Find the Factors of 205?
To find the factors of 205, we will have to find the list of numbers that would divide 205 without leaving any remainder.
- 205/41 = 5; therefore, 41 is a factor of 205 and 5 is also a factor of 205.
- 205/1 = 205; therefore, 1 is a factor of 205 and 205 is also a factor of 205.

Factors of 205 by Prime Factorization
- 205 ÷ 5 = 41
Further dividing 41 by 5 gives a non-zero remainder. So we stop the process and continue dividing the number 41 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 205 can be written as 51 × 411 where 5, 41 are prime.
Factors of 205 in Pairs
Pair factors of 205 are the pairs of numbers that when multiplied give the product 205. The factors of 205 in pairs are:
- 1 × 205 = (1, 205)
- 5 × 41 = (5, 41)
Negative pair factors of 205 are:
- -1 × -205 = (-1, -205)
- -5 × -41 = (-5, -41)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
Factors of 205 Solved Examples
