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 1105, how they are used in real life, and tips to learn them quickly.

What are the Factors of 1105?

The numbers that divide 1105 evenly are known as factors of 1105.

A factor of 1105 is a number that divides the number without a remainder.

The factors of 1105 are 1, 5, 13, 17, 65, 85, 221, and 1105.

Negative factors of 1105: -1, -5, -13, -17, -65, -85, -221, and -1105.

Prime factors of 1105: 5, 13, and 17.

Prime factorization of 1105: 5 × 13 × 17.

The sum of factors of 1105: 1 + 5 + 13 + 17 + 65 + 85 + 221 + 1105 = 1512

How to Find Factors of 1105?

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

  • Finding factors using multiplication
  • Finding factors using the 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 1105. Identifying the numbers that are multiplied to get the number 1105 is the multiplication method.

Step 1: Multiply 1105 by 1, 1105 × 1 = 1105.

Step 2: Check for other numbers that give 1105 after multiplying

5 × 221 = 1105

13 × 85 = 1105

17 × 65 = 1105

Therefore, the positive factor pairs of 1105 are: (1, 1105), (5, 221), (13, 85), (17, 65).

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 the simple division method 

Step 1: Divide 1105 by 1, 1105 ÷ 1 = 1105.

Step 2: Continue dividing 1105 by the numbers until the remainder becomes 0.

1105 ÷ 1 = 1105

1105 ÷ 5 = 221

1105 ÷ 13 = 85

1105 ÷ 17 = 65

Therefore, the factors of 1105 are: 1, 5, 13, 17, 65, 85, 221, 1105.

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 1105 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1105 ÷ 5 = 221

221 ÷ 13 = 17

17 ÷ 17 = 1

The prime factors of 1105 are 5, 13, and 17.

The prime factorization of 1105 is: 5 × 13 × 17.

Factor Tree

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

Step 1: Firstly, 1105 is divided by 5 to get 221.

Step 2: Now divide 221 by 13 to get 17.

Step 3: Divide 17 by 17 to get 1. Here, 17 is the smallest prime number, that cannot be divided anymore.

So, the prime factorization of 1105 is: 5 × 13 × 17.

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 1105: (1, 1105), (5, 221), (13, 85), (17, 65).

Negative factor pairs of 1105: (-1, -1105), (-5, -221), (-13, -85), (-17, -65).

Common Mistakes and How to Avoid Them in Factors of 1105

Problem 2

A garden is rectangular, the length of the garden is 17 meters and the total area is 1105 square meters. Find the width.

Okay, lets begin

65 meters.

Explanation

To find the width of the garden, we use the formula, Area = length × width 1105 = 17 × width

To find the value of width, we need to shift 17 to the left side.

1105/17 = width

Width = 65.
