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 1729, how they are used in real life, and tips to learn them quickly.

What are the Factors of 1729?

The numbers that divide 1729 evenly are known as factors of 1729.

A factor of 1729 is a number that divides the number without remainder.

The factors of 1729 are 1, 7, 13, 19, 91, 133, 247, and 1729.

Negative factors of 1729: -1, -7, -13, -19, -91, -133, -247, and -1729.

Prime factors of 1729: 7, 13, and 19.

Prime factorization of 1729: 7 × 13 × 19.

The sum of factors of 1729: 1 + 7 + 13 + 19 + 91 + 133 + 247 + 1729 = 2240

How to Find Factors of 1729?

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 1729. Identifying the numbers which are multiplied to get the number 1729 is the multiplication method.

Step 1: Multiply 1729 by 1, 1729 × 1 = 1729.

Step 2: Check for other numbers that give 1729 after multiplying

7 × 247 = 1729

13 × 133 = 1729

19 × 91 = 1729

Therefore, the positive factor pairs of 1729 are: (1, 1729), (7, 247), (13, 133), (19, 91).

All these factor pairs result in 1729.

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 1729 by 1, 1729 ÷ 1 = 1729.

Step 2: Continue dividing 1729 by the numbers until the remainder becomes 0.

1729 ÷ 1 = 1729

1729 ÷ 7 = 247

1729 ÷ 13 = 133

1729 ÷ 19 = 91

Therefore, the factors of 1729 are: 1, 7, 13, 19, 91, 133, 247, 1729.

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 1729 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1729 ÷ 7 = 247

247 ÷ 13 = 19

19 ÷ 19 = 1

The prime factors of 1729 are 7, 13, and 19.

The prime factorization of 1729 is: 7 × 13 × 19.

Factor Tree

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

Step 1: Firstly, 1729 is divided by 7 to get 247.

Step 2: Now divide 247 by 13 to get 19.

Step 3: Divide 19 by 19 to get 1. Here, 19 is the smallest prime number, that cannot be divided anymore.

So, the prime factorization of 1729 is: 7 × 13 × 19.

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 1729: (1, 1729), (7, 247), (13, 133), and (19, 91).

Negative factor pairs of 1729: (-1, -1729), (-7, -247), (-13, -133), and (-19, -91).

Problem 2

A plot of land is rectangular, the length of the plot is 13 meters and the total area is 1729 square meters. Find the width?

Okay, lets begin

133 meters.

Explanation

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

Area = length × width

1729 = 13 × width

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

1729/13 = width

Width = 133.
