A factor of 1689 is a number that divides the number without remainder.

The factors of 1689 are 1, 3, 563, and 1689.

Negative factors of 1689: -1, -3, -563, and -1689.

Prime factors of 1689: 3 and 563.

Prime factorization of 1689: 3 × 563.

The sum of factors of 1689: 1 + 3 + 563 + 1689 = 2256

How to Find Factors of 1689?

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 1689. Identifying the numbers which are multiplied to get the number 1689 is the multiplication method.

Step 1: Multiply 1689 by 1, 1689 × 1 = 1689.

Step 2: Check for other numbers that give 1689 after multiplying 3 × 563 = 1689

Therefore, the positive factor pairs of 1689 are: (1, 1689) and (3, 563).

These factor pairs result in 1689.

For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given numbers by 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 1689 by 1, 1689 ÷ 1 = 1689.

Step 2: Continue dividing 1689 by the numbers until the remainder becomes 0.

1689 ÷ 1 = 1689

1689 ÷ 3 = 563

Therefore, the factors of 1689 are: 1, 3, 563, and 1689.

Prime Factors and Prime Factorization

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

Using Prime Factorization: In this process, prime factors of 1689 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1689 ÷ 3 = 563

563 ÷ 563 = 1

The prime factors of 1689 are 3 and 563.

The prime factorization of 1689 is: 3 × 563.

Factor Tree

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

Step 1: Firstly, 1689 is divided by 3 to get 563.

Step 2: Then divide 563 by 563 to get 1. Here, 3 and 563 are the prime numbers, and they cannot be divided anymore. So, the prime factorization of 1689 is: 3 × 563.

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 1689: (1, 1689) and (3, 563).

Negative factor pairs of 1689: (-1, -1689) and (-3, -563).
