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 100 - The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100

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.

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.
