What are Factors of 404?
Factors of 404 are pairs of those numbers whose products result in 404. These factors are either prime numbers or composite numbers.
How to Find the Factors of 404?
To find the factors of 404, we will have to find the list of numbers that would divide 404 without leaving any remainder.
- 404/101 = 4; therefore, 101 is a factor of 404 and 4 is also a factor of 404.
- 404/2 = 202; therefore, 2 is a factor of 404 and 202 is also a factor of 404.
Similarly we can find other factors. Hence, the factors of 404 are 1, 2, 4, 101, 202, 404.

Factors of 404 by Prime Factorization
The number 404 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 404. The first step is to divide the number 404 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.
- 404 ÷ 2 = 202
- 202 ÷ 2 = 101
Further dividing 101 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 101 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 404 can be written as 22 × 1011 where 2, 101 are prime.
Factors of 404 in Pairs
Pair factors of 404 are the pairs of numbers that when multiplied give the product 404. The factors of 404 in pairs are:
- 1 × 404 = (1, 404)
- 2 × 202 = (2, 202)
- 4 × 101 = (4, 101)
Negative pair factors of 404 are:
- -1 × -404 = (-1, -404)
- -2 × -202 = (-2, -202)
- -4 × -101 = (-4, -101)
NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
Factors of 404 Solved Examples
Example 1: How many factors are there for 404?
Solution:
The factors of 404 are 1, 2, 4, 101, 202, 404. Therefore, 404 has 6 factors.
Example 2: Find the Lowest Common Multiple (LCM) and Greatest Common Factor (GCF) of 404 and 389.
Solution:
The factors of 404 are 1, 2, 4, 101, 202, 404 and factors of 389 are 1, 389.
Therefore, the Lowest Common Multiple (LCM) of 404 and 389 is 157156 and Greatest Common Factor (GCF) of 404 and 389 is 1.
Example 3: Find if 2, 4, 202 and 305 are factors of 404.
Solution:
When we divide 404 by 305 it leaves a remainder. Therefore, the number 305 is not a factor of 404. All numbers except 305 are factors of 404.
Example 4: Find the product of all the prime factors of 404.
Solution:
Since, the prime factors of 404 are 2, 101. Therefore, the product of prime factors = 2 × 101 = 202.
