Factors of 163: Prime Factorization, Methods, and Examples

The factors of 163 are the numbers which produce zero as a remainder when 163 is divided from such numbers. They also produce a whole number quotient. Together, the quotient and the divisor form a factor pair. 

The number 163 is a prime number so it only has two factors. Let’s take a look at these factors in this article and discuss how to evaluate them.

Prime Factorization: 1 x 63

In this article, we will learn about the factors of 163 and how to find them using various techniques such as upside-down division, prime factorization, and factor tree.

What Are the Factors of 163?

The factors of 163 are 1 and 163. All of these numbers are the factors as they do not leave any remainder when divided by 163.

The factors of 163 are classified as prime numbers and composite numbers. The prime factors of the number 163 can be determined using the technique of prime factorization.

How To Find the Factors of 163?

You can find the factors of 163 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 163, create a list containing the numbers that are exactly divisible by 163 with zero remainders. One important thing to note is that 1 and 163 are the 163’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 163 are determined as follows:

\[\dfrac{163}{1} = 163\]

\[\dfrac{163}{163} = 1\]

Therefore, 1 and 163 are the factors of 163.

Total Number of Factors of 163

For 163 there are 2 positive factors and 2 negative ones. So in total, there are 4 factors of 163. 

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

  1. Find the 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 163 is given as:

Factorization of 163 is 1 x 163.

The exponent of 1 and 163 is 1.

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

Therefore, the total number of factors of 163 is 4, where 2 are positive factors and 2 are negative factors. 

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 163 by Prime Factorization

The number 163 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 163 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 163, 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 163 can be expressed as:

163 = 1 x 163

Factors of 163 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.

For 163, the factor pairs can be found as:

1 x 163 = 163

The possible factor pair of 163 is given as (1, 163).

All these numbers in pairs, when multiplied, give 163 as the product.

The negative factor pairs of 163 are given as:

-1 x -163 = 163

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 -163 are called negative factors of 163.

The list of all the factors of 163 including positive as well as negative numbers is given below.
