Prime factors of 1365: 3, 5, 7, and 13.

Prime factorization of 1365: 3 × 5 × 7 × 13.

The sum of factors of 1365: 1 + 3 + 5 + 7 + 13 + 21 + 35 + 39 + 65 + 91 + 195 + 273 + 455 + 1365 = 2568

How to Find Factors of 1365?

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 1365. Identifying the numbers which are multiplied to get the number 1365 is the multiplication method.

Step 1: Multiply 1365 by 1, 1365 × 1 = 1365.

Step 2: Check for other numbers that give 1365 after multiplying

3 × 455 = 1365

5 × 273 = 1365

7 × 195 = 1365

13 × 105 = 1365

Therefore, the positive factor pairs of 1365 are: (1, 1365), (3, 455), (5, 273), (7, 195), (13, 105).

For every positive factor, there is a negative factor.

Finding Factors Using Division Method

Dividing the given numbers with 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 a simple division method

Step 1: Divide 1365 by 1, 1365 ÷ 1 = 1365.

Step 2: Continue dividing 1365 by the numbers until the remainder becomes 0.

1365 ÷ 1 = 1365

1365 ÷ 3 = 455

1365 ÷ 5 = 273

1365 ÷ 7 = 195

1365 ÷ 13 = 105

Therefore, the factors of 1365 are: 1, 3, 5, 7, 13, 21, 35, 39, 65, 91, 195, 273, 455, and 1365.

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 1365 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.

1365 ÷ 3 = 455

455 ÷ 5 = 91

91 ÷ 7 = 13

13 ÷ 13 = 1

The prime factors of 1365 are 3, 5, 7, and 13.

The prime factorization of 1365 is: 3 × 5 × 7 × 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, 1365 is divided by 3 to get 455.

Step 2: Now divide 455 by 5 to get 91.

Step 3: Then divide 91 by 7 to get 13. Here, 13 is the smallest prime number, that cannot be divided anymore. So, the prime factorization of 1365 is: 3 × 5 × 7 × 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 1365: (1, 1365), (3, 455), (5, 273), (7, 195), and (13, 105).

Negative factor pairs of 1365: (-1, -1365), (-3, -455), (-5, -273), (-7, -195), and (-13, -105).

Common Mistakes and How to Avoid Them in Factors of 1365

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 13 friends and 1365 candies. How will they divide it equally?

Okay, lets begin

They will get 105 candies each.

Explanation

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

1365/13 = 105

Problem 2

A field is rectangular, the length of the field is 39 meters and the total area is 1365 square meters. Find the width?

Okay, lets begin

35 meters.

Explanation

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

Area = length × width

1365 = 39 × width

To find the value of width, we need to shift 39 to the left side.

1365/39 = width

Width = 35.
