Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing the items equally, arranging things, etc. In this topic, we will learn about the factors of 483, how they are used in real life, and the tips to learn them quickly.

What are the Factors of 483?

The numbers that divide 483 evenly are known as factors of 483.

A factor of 483 is a number that divides the number without remainder.

The factors of 483 are 1, 3, 7, 21, 23, 69, 161, and 483.

Negative factors of 483: -1, -3, -7, -21, -23, -69, -161, and -483.

Prime factors of 483: 3, 7, and 23.

Prime factorization of 483: 3 × 7 × 23.

The sum of factors of 483: 1 + 3 + 7 + 21 + 23 + 69 + 161 + 483 = 768

How to Find Factors of 483?

Factors can be found using different methods. Mentioned below are some commonly used methods:

  • Finding factors using multiplication
     
  • Finding factors using division method
     
  • Prime factors and Prime factorization

Finding Factors Using Multiplication

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 483. Identifying the numbers which are multiplied to get the number 483 is the multiplication method.

Step 1: Multiply 483 by 1, 483 × 1 = 483.

Step 2: Check for other numbers that give 483 after multiplying

3 × 161 = 483

7 × 69 = 483

21 × 23 = 483

Therefore, the positive factor pairs of 483 are: (1, 483), (3, 161), (7, 69), (21, 23).

All these factor pairs result in 483.

For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which results as whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 483 by 1, 483 ÷ 1 = 483.

Step 2: Continue dividing 483 by the numbers until the remainder becomes 0.

483 ÷ 1 = 483

483 ÷ 3 = 161

483 ÷ 7 = 69

483 ÷ 21 = 23

Therefore, the factors of 483 are: 1, 3, 7, 21, 23, 69, 161, 483.

Prime Factors and Prime Factorization

The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods:

Using Prime Factorization: In this process, prime factors of 483 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

483 ÷ 3 = 161

161 ÷ 7 = 23

23 ÷ 23 = 1

The prime factors of 483 are 3, 7, and 23.

The prime factorization of 483 is: 3 × 7 × 23.

Factor Tree

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows -

Step 1: Firstly, 483 is divided by 3 to get 161.

Step 2: Now divide 161 by 7 to get 23.

Step 3: Here, 23 is the smallest prime number, that cannot be divided anymore.

So, the prime factorization of 483 is: 3 × 7 × 23.

Factor Pairs Two numbers that are multiplied to give a specific number are called factor pairs.

Both positive and negative factors constitute factor pairs.

Positive factor pairs of 483: (1, 483), (3, 161), (7, 69), and (21, 23).

Negative factor pairs of 483: (-1, -483), (-3, -161), (-7, -69), and (-21, -23).

Common Mistakes and How to Avoid Them in Factors of 483

Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.

Problem 1

There are 3 boxes and 483 apples. How will they divide it equally?

Okay, lets begin

They will get 161 apples each.

Explanation

To divide the apples equally, we need to divide the total apples with the number of boxes.

483/3 = 161

Well explained 👍

Problem 2

A field is rectangular, the length of the field is 21 meters and the total area is 483 square meters. Find the width?

Okay, lets begin

23 meters.

Explanation

To find the width of the field, we use the formula,

Area = length × width

483 = 21 × width

To find the value of width, we need to shift 21 to the left side.

483/21 = width

Width = 23.
