Prime factorization of 1533: 3 × 3 × 13 × 13.

The sum of factors of 1533: 1 + 3 + 9 + 13 + 27 + 39 + 51 + 117 + 171 + 459 + 511 + 1533 = 2934

How to Find Factors of 1533?

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

  1. Finding factors using multiplication
  2. Finding factors using the 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 1533. Identifying the numbers which are multiplied to get the number 1533 is the multiplication method.

Step 1: Multiply 1533 by 1, 1533 × 1 = 1533.

Step 2: Check for other numbers that give 1533 after multiplying

3 × 511 = 1533

9 × 171 = 1533

13 × 117 = 1533

27 × 57 = 1533

Therefore, the positive factor pairs of 1533 are: (1, 1533), (3, 511), (9, 171), (13, 117), (27, 57). All these factor pairs result in 1533. 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 as whole numbers as factors. Factors can be calculated by following a simple division method -

Step 1: Divide 1533 by 1, 1533 ÷ 1 = 1533.

Step 2: Continue dividing 1533 by the numbers until the remainder becomes 0.

1533 ÷ 1 = 1533

1533 ÷ 3 = 511

1533 ÷ 9 = 171

1533 ÷ 13 = 117

1533 ÷ 27 = 57

Therefore, the factors of 1533 are: 1, 3, 9, 13, 27, 39, 51, 117, 171, 459, 511, 1533.

Prime Factors and Prime Factorization

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

Using Prime Factorization: In this process, prime factors of 1533 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1533 ÷ 3 = 511

511 ÷ 13 = 39

39 ÷ 3 = 13

13 ÷ 13 = 1

The prime factors of 1533 are 3, 13, and 39. The prime factorization of 1533 is: 3 × 3 × 13 × 13.

Factor Tree

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

Step 1: Firstly, 1533 is divided by 3 to get 511.

Step 2: Now divide 511 by 13 to get 39.

Step 3: Then divide 39 by 3 to get 13. Here, 13 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1533 is: 3 × 3 × 13 × 13.

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 1533: (1, 1533), (3, 511), (9, 171), (13, 117), and (27, 57).
  • Negative factor pairs of 1533: (-1, -1533), (-3, -511), (-9, -171), (-13, -117), and (-27, -57).

Common Mistakes and How to Avoid Them in Factors of 1533

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 1533 candies. How will they divide them equally?

Okay, lets begin

Each team will get 511 candies.

Explanation

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

1533/3 = 511

Problem 2

A field is rectangular, the length of the field is 13 meters and the total area is 1533 square meters. Find the width?

Okay, lets begin

117 meters.

Explanation

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

Area = length × width

1533 = 13 × width

To find the value of width, we need to shift 13 to the left side.

1533/13 = width

Width = 117.
