Factors are the numbers that divide any given number evenly without remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will learn about the factors of 903, how they are used in real life, and the tips to learn them quickly.

What are the Factors of 903?

The numbers that divide 903 evenly are known as factors of 903. A factor of 903 is a number that divides the number without remainder. The factors of 903 are 1, 3, 11, 33, 41, 123, 271, and 903.

Negative factors of 903: -1, -3, -11, -33, -41, -123, -271, and -903.

Prime factors of 903: 3, 11, and 41.

Prime factorization of 903: 3 × 11 × 41.

The sum of factors of 903: 1 + 3 + 11 + 33 + 41 + 123 + 271 + 903 = 1386

How to Find Factors of 903?

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

  1. Finding factors using multiplication
  2. Finding factors using division method
  3. 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 903. Identifying the numbers which are multiplied to get the number 903 is the multiplication method.

Step 1: Multiply 903 by 1, 903 × 1 = 903.

Step 2: Check for other numbers that give 903 after multiplying  

3 × 301 = 903  

11 × 82 = 903  

33 × 27 = 903

Therefore, the positive factor pairs of 903 are: (1, 903), (3, 301), (11, 82), (33, 27). 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 result in whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 903 by 1, 903 ÷ 1 = 903.

Step 2: Continue dividing 903 by the numbers until the remainder becomes 0.

903 ÷ 1 = 903

903 ÷ 3 = 301

903 ÷ 11 = 82

903 ÷ 33 = 27

Therefore, the factors of 903 are: 1, 3, 11, 33, 41, 123, 271, 903.

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 903 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

903 ÷ 3 = 301

301 ÷ 11 = 27.36 (check the next prime number)

301 ÷ 41 = 7.34 (check the next prime number)

301 ÷ 271 = 1.11 (not valid) Revisiting

since 903 = 3 × 11 × 41.

Factor Tree

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

Step 1: Firstly, 903 is divided by 3 to get 301.

Step 2: Now divide 301 by 11 to get 27.36 (check the next prime number)

Step 3: Next divide 301 by 41 to get 7.34 (check the next prime number)

Step 4: Finally, 301 can be directly divided by 271. So, the prime factorization of 903 is: 3 × 11 × 41.

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 903: (1, 903), (3, 301), (11, 82), (33, 27).
  • Negative factor pairs of 903: (-1, -903), (-3, -301), (-11, -82), (-33, -27).

Common Mistakes and How to Avoid Them in Factors of 903

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 teams and 903 points. How will they distribute the points equally?

Okay, lets begin

Each team will get 301 points.

Explanation

To distribute the points equally, we need to divide the total points by the number of teams.

903/3 = 301

Well explained 👍

Problem 2

A rectangular garden has a width of 11 meters and a total area of 903 square meters. Find the length.

Okay, lets begin

82 meters.

Explanation

To find the length of the garden, we use the formula,

Area = length × width

903 = 11 × length

To find the value of length, we need to shift 11 to the left side.

903/11 = length

Length = 82.

Well explained 👍

Problem 3

There are 33 boxes and 903 items. How many items will be in each box?

Okay, lets begin

Each box will have 27 items.

Explanation

To find the items in each box, divide the total items by the number of boxes.

903/33 = 27

Well explained 👍

Problem 4

In a class, there are 903 students, and 41 groups. How many students are there in each group?

Okay, lets begin

There are 22 students in each group.

Explanation

Dividing the students by the total groups, we will get the number of students in each group.

903/41 = 22

Well explained 👍

Problem 5

903 books need to be arranged in 11 shelves. How many books will go on each shelf?
