Prime Factorization: 3 x 191

In this article, we will learn about the factors of 573 and how to find them using various techniques such as upside-down division, prime factorization, and factor tree.

What Are the Factors of 573?

The factors of 573 are 1, 3, 191, and 573. These numbers are the factors as they do not leave any remainder when divided by 573.

The factors of 573 are classified as prime numbers and composite numbers. The prime factors of the number 573 can be determined using the prime factorization technique.

How To Find the Factors of 573?

You can find the factors of 573 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 573, create a list containing the numbers that are exactly divisible by 573 with zero remainders. One important thing to note is that 1 and 573 are the 573’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 573 are determined as follows:

\[\dfrac{573}{1} = 573\]

\[\dfrac{573}{3} = 191\]

\[\dfrac{573}{191} = 3\]

\[\dfrac{573}{573} = 1\]

Therefore, 1, 3, 191, and 573 are the factors of 573.

Total Number of Factors of 573

For 573, there are four positive factors and four negative ones. So in total, there are eight factors of 573. 

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 573 is given as:

Factorization of 573 is 1 x 3 x 191.

The exponent of 1, 3, and 191 is 1.

Adding 1 to each and multiplying them together results in 8.

Therefore, the total number of factors of 573 is eight whereas four are positive, and four 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 573 by Prime Factorization

The number 573 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.prime factorization of 573

Before finding the factors of 573 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 573, 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 573 can be expressed as:

573 = 3 x 191

Factors of 573 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.Factors of 573 in Pairs

For 573, the factor pairs can be found as:

1 x 573 = 573

3 x 191 = 573

The possible factor pairs of 573 are given as (1, 573) and (3, 191).

All these numbers in pairs, when multiplied, give 573 as the product.

The negative factor pairs of 573 are given as:

-1 x -573 = 573 

-3 x -191 = 573

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, -3, -191, and -573 are called negative factors of 573.

The list of all the factors of 573, including positive as well as negative numbers, is given below.
