Factors of 173: Prime Factorization, Methods, and Examples

The factors of 173 are numbers that when divided by 173 leave zero as the remainder. This means the numbers that completely divide the given number are named as its factors. The factors of the given number can be positive as well as negative provided that the given number is achieved upon multiplication of two-factor integers.

Factors of 173

Here are the factors of number 173.

Factors of 173: 1, 173

Negative Factors of 173

The negative factors of 173 are similar to its positive factors, just with a negative sign.

Negative Factors of 173: -1, -173

Prime Factorization of 173

The prime factorization of 173 is the way of expressing its prime factors in the product form.

Prime Factorization: 1 x 173

In this article, we will learn about the factors of 173 and how to find them using various techniques such as upside-down division, prime factorization, and factor tree.

What Are the Factors of 173?

The factors of 173 are 1, and 173. It has only two factors as 173 itself is a prime number.

The prime factors of the number 173 can be determined using the technique of prime factorization.

How To Find the Factors of 173?

You can find the factors of 173 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 173, create a list containing the numbers that are exactly divisible by 173 with zero remainders. One important thing to note is that 1 and 173 are the 173’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 173 are determined as follows:

\[\dfrac{173}{1} = 173\]

As 173 is a prime number it is only divisible by 1 and 173. Therefore 1 and 173 are the only factors of 173.

Total Number of Factors of 173

For 173 there are 2 positive factors and 2 negative ones. So in total, there are 4 factors of 173. 

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 173 is given as:

Factorization of 173 is 1 x 173.

The exponent of 1 and 173 is 1.

Adding 1 to each and multiplying them together results in 4.

Therefore, the total number of factors of 173 is 4. 2 are positive and 2 factors are negative.

Important Notes

Here are some important 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 173 by Prime Factorization

The number 173 is a prime number. Prime factorization is a useful technique for finding the number’s prime factors and expressing the number as the product of its prime factors.

Before finding the factors of 173 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 173, start dividing by its smallest 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 173 can be expressed as:

\[  173 = 1 \times 173\]

Factors of 173 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 of the given numbers.

The number 173 has only 2 factors therefore, it has only 1- factor pair. 

\[ 1 \times 173 = 173 \]

The possible factor pair of 173 is given as (1, 173).

The negative factor pair of 173 is given as:

\[ -1 \times -173 = 173 \]

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 and -173 are called negative factors of 173.

The list of all the factors of 173 including positive as well as negative numbers is given below.
