## What Are the Factors of 404?

The factors of 404 are 1, 2, 4, 101, 202, and 404. These numbers are the factors as they do not leave any remainder when divided by 404.

The factors of 404 are classified as prime numbers and composite numbers. The prime factors of the number 404 can be determined using the prime factorization technique.

## How To Find the Factors of 404?

You can find the factors of 404 by using the rules of divisibility. The divisibility rule states that any number, when divided by any other natural number, is said to be divisible by the number if the quotient is the whole number and the resulting remainder is zero.

To find the factors of 404, create a list containing the numbers that are exactly divisible by 404 with zero remainders. One important thing to note is that 1 and 404 are the 404’s factors as every natural number has 1 and the number itself as its factor.

1 is also called the universal factor of every number. The factors of 404 are determined as follows:

$\dfrac{404}{1} = 404$

$\dfrac{404}{2} = 202$

$\dfrac{404}{4} = 101$

Therefore, 1, 2, 4, 101, 202, and 404  are the factors of 404.

### Total Number of Factors of 404

For 404, there are six positive factors and n negative ones. So in total, there are twelve factors of 404.

To find the total number of factors of the given number, follow the procedure mentioned below:

1. Find the factorization/prime factorization of the given number.
2. Demonstrate the prime factorization of the number in the form of exponent form.
3. Add 1 to each of the exponents of the prime factor.
4. Now, multiply the resulting exponents together. This obtained product is equivalent to the total number of factors of the given number.

By following this procedure, the total number of factors of 404 is given as:

Factorization of 404 is 1 x 2$^2$ x 101.

The exponent of 1 and 101 is 1. The exponent of 2 is 2.

Adding 1 to each and multiplying them together results in twelve.

Therefore, the total number of factors of 404 is 12. Six are positive, and six factors are negative.

### Important Notes

Here are some essential points that must be considered while finding the factors of any given number:

• The factor of any given number must be a whole number.
• The factors of the number cannot be in the form of decimals or fractions.
• Factors can be positive as well as negative.
• Negative factors are the additive inverse of the positive factors of a given number.
• The factor of a number cannot be greater than that number.
• Every even number has 2 as its prime factor, the smallest prime factor.

## Factors of 404 by Prime Factorization

The number 404 is a composite. Prime factorization is a valuable technique for finding the number’s prime factors and expressing the number as the product of its prime factors. Before finding the factors of 404 using prime factorization, let us find out what prime factors are. Prime factors are the factors of any given number that are only divisible by 1 and themselves.

To start the prime factorization of 404, start dividing by its most minor prime factor. First, determine that the given number is either even or odd. If it is an even number, then 2 will be the smallest prime factor.

Continue splitting the quotient obtained until 1 is received as the quotient. The prime factorization of 404 can be expressed as:

404 = 2 x 2 x 101

## Factors of 404 in Pairs

The factor pairs are the duplet of numbers that, when multiplied together, result in the factorized number. Factor pairs can be more than one depending on the total number of factors given. For 404, the factor pairs can be found as:

1 x 404 = 404

2 x 202 = 404

4 x 101 = 404

The possible factor pairs of 404 are given as (1, 404), (2, 202), and (4, 101).

All these numbers in pairs, when multiplied, give 404 as the product.

The negative factor pairs of 404 are given as:

-1 x -404 = 404

-2 x -202 = 404

-4 x -101 = 404

It is important to note that in negative factor pairs, the minus sign has been multiplied by the minus sign, due to which the resulting product is the original positive number. Therefore, 1, -2, -4, -101, -202, and -404  are called negative factors of 404.

The list of all the factors of 404, including positive as well as negative numbers, is given below.

Factor list of 404: 1, 1, 2, -2, 4, -4, 101, -101, 202, -202, 404, and -404
