A number that can divide another number evenly without leaving any remainder is called a factor. Factors are useful in many real-life situations, such as construction, where it is used to determine the dimensions of materials to avoid waste. Next, let's discuss the factors of 253.

What are the Factors of 253?

Prime numbers can have just two factors, which are 1 and the number itself. Composite numbers have more than two factors. Now, let us learn more about the factors of 253

  • Negative factors of 253: -1, -11, -23, and -253
  • Prime factors of 253: 11 and 23
  • Prime factorization of 253:  11 × 23
  • The sum of factors of 253: 11 + 23 =34
     

How to Find the Factors of 253?

For finding factors, school kids use different methods for easy calculation. A few commonly used methods are as follows:

  1. Use of Multiplication Method
  2. Use of Division Method
  3. Use of Prime Factors and Prime Factorization.

So, here we discuss a detailed explanation of the following methods:
 

Finding Factors Using Multiplication Method

So in the multiplication method, we will try to find out what numbers will multiply together, and give us the value 253. We will check the factors step by step:


Step 1: Start to multiply with numbers, which gives the value of 253.

Start with 1, and continue to multiply with other numbers.


1×253=253
11×23=253


Step 2: After the calculation, we get these numbers, the factors of 253.


Step 3: The positive factor pairs of 253 found through multiplication are (1, 253) and (11, 23).


Step 4: The negative factor pairs of 253 are (-1, -253), (-11, -23)

Finding Factors Using Division Method

Using this method we will break down the given number till our remainder is zero. Let us go through the step-by-step process to find the factors of 253:


Step 1: Divide 253 by smaller numbers and see if there is any remainder. E.g., 253/1 = 253. 


Step 2: We will continue in the same way and check for other numbers as well. For 253, the factors are 1, 11, 23, and 253. Because 253 can be divided evenly by these numbers.
 

Prime Factors and Prime Factorization

The prime factors of 253 are 11 and 23. The prime factors can be found using the methods given below:

Prime Factorization


Factor Tree


By Using Prime Factorization: When using this method, the number is divided by its prime numbers until it is factored completely by l.


11 is the smallest prime number, so start dividing with eleven. And then continue to divide with other prime numbers.
253 ÷11=23


The prime factorization of 253 is :
253 = 11 × 23


Finally, using the prime factorization method, the prime factors of 253 are 11 and 23.

Using Factor Tree:

A factor tree is a visual representation of breaking a number into its prime factors. It is an easy and simple way to present the factors


Step 1: 253 divided by 11 gives us the answer 23.


Step 2: Since 23 is a prime number, it cannot be divided further.


 The prime factorization of 253 is written below : 


253 = 11 × 23
 

Factor Pairs Of 253

Every number has either a positive or negative factor. Let us look at those sets of factors.


Positive pair Factors:  (1, 253), (11, 23)
Negative pair Factors:(-1, -253), (-11, -23)
