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 1389, how they are used in real life, and the tips to learn them quickly.

What are the Factors of 1389?

The numbers that divide 1389 evenly are known as factors of 1389.

A factor of 1389 is a number that divides the number without remainder.

The factors of 1389 are 1, 3, 463, and 1389.

Negative factors of 1389: -1, -3, -463, and -1389.

Prime factors of 1389: 3 and 463.

Prime factorization of 1389: 3 × 463.

The sum of factors of 1389: 1 + 3 + 463 + 1389 = 1856

How to Find Factors of 1389?

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 1389. Identifying the numbers which are multiplied to get the number 1389 is the multiplication method.

Step 1: Multiply 1389 by 1, 1389 × 1 = 1389.

Step 2: Check for other numbers that give 1389 after multiplying 3 × 463 = 1389

Therefore, the positive factor pairs of 1389 are: (1, 1389) and (3, 463).

All these factor pairs result in 1389.

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 1389 by 1, 1389 ÷ 1 = 1389.

Step 2: Continue dividing 1389 by the numbers until the remainder becomes 0.

1389 ÷ 1 = 1389

1389 ÷ 3 = 463

Therefore, the factors of 1389 are: 1, 3, 463, 1389.

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 1389 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1389 ÷ 3 = 463

463 ÷ 463 = 1

The prime factors of 1389 are 3 and 463.

The prime factorization of 1389 is: 3 × 463.

Factor Tree

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

Step 1: Firstly, 1389 is divided by 3 to get 463.

Step 2: Now divide 463 by 463 to get 1. Here, 463 is a prime number, that cannot be divided anymore.

So, the prime factorization of 1389 is: 3 × 463.

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 1389: (1, 1389), (3, 463).

Negative factor pairs of 1389: (-1, -1389), (-3, -463).
