Factors of 80

Professor Greenline Explaining Math Concepts

The numbers multiplied to get 80 as the product are the factors of 80. So, in daily life, factors are used to distribute teams in groups. Sometimes, for recipes, cooks apply the factors' methods to adjust ingredients properly.

What are the factors of 80?

The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80.

 

Negative factors of 80- There’s always a corresponding negative factor for each positive factor of 80.


Negative factors of 80: -1, -2, -4, -5, -8, -10, -16, -20, -40, -80

 

Prime Factors of 80- The prime numbers are the prime factors, that can only be divided by 1 and the number itself.


Prime factors of 80: 2, 5

 

Prime Factorization of 80- Prime factorization breaks 80 into its prime factors and expresses its product using exponents.


80 is prime factorized as 24 × 51

 

An overview of the factors of 80:

How to find the Factors of 80

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 
     
Professor Greenline from BrightChamps

Finding Factors Using Multiplication Method

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 80. Identifying the numbers which are multiplied to get the number 80 is the multiplication method.


Step 1: Multiply 80 by 1, 80 × 1 = 80.


Step 2: Check for other numbers that give 80 after multiplying


2 × 40 = 80
4 × 20 = 80
5 × 16 = 80
8 × 10 = 80


Therefore, the positive factor pairs of 80 are: (1, 80), (2, 40), (4, 20), (5, 16), (8, 10). All these factor pair result in 80. For every positive factor, there is a negative factor.
 

Factors of 80 by multiplication method

So the pair of numbers will be (1,80), (2,40), (4,20), (5,16) and (8,10)
 

Professor Greenline from BrightChamps

Finding Factors Using Division Method

Dividing the given numbers with the whole numbers until the remainder becomes zero and listing out the numbers which results as a whole numbers as factors. Factors can be calculated by following simple division method - 


Step 1: Divide 80 by 1, 80 ÷ 1 = 80.


Step 2: Continue dividing 80 by the numbers until the remainder becomes 0.


80 ÷ 1 = 80
80 ÷ 2 = 40
80 ÷ 4 = 20
80 ÷ 5 = 16
80 ÷ 8 = 10


Therefore, the factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

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
  • Using factor tree

 

Using Prime Factorization: In this process, prime factors of 80 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1.


80 ÷ 2 = 40
40 ÷ 2 = 20
20 ÷ 2 = 10
10 ÷ 2 = 5
5 ÷ 5 = 1

 

The prime factors of 80 are 2 and 5.


The prime factorization of 80 is: 24 × 5.
 

Factors of 80 using factor tree

 

Professor Greenline from BrightChamps

Factor Tree

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


Step 1: Firstly, 80 is divided by 2 to get 40.


Step 2: Now divide 40 by 2 to get 20.


Step 3: Then divide 20 by 2 to get 10.


Step 4: Divide 10 by 2 to get 5.


Here, 5 is the smallest prime numbers, that cannot be divided anymore.


So, the prime factorization of 80 is: 24 × 5.

 

Factor Pairs: Two numbers that are multiplied to give a specific number are called as factor pairs. Both positive and negative factors constitute factor pairs. 


Positive factor pairs of 80: (1, 80), (2, 40), (4, 20), (5, 16), and (8, 10).

Negative factor pairs of 80: (-1, -80), (-2, -40), (-4, -20), (-5, -16), and (-8, -10).

 

 

 

 

Factor Pairs- Factor pairs of 80 are a team of 2 factors each. Their product will be equal to the number, that is 80.

 

Positive Factor Pairs: (1,80), (2,40), (4,20), (5,16), (8,10)


Negative Factor Pairs: (-1,-80), (-2, -40), (-4, -20), (-5, -16), (-8, -10)

Problem 1

There are 8 friends and 80 cookies. How will they divide it equally?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

 They will get 10 cookies each.
 

Explanation

 To divide the cookies equally, we need to divide the total cookies with the number of friends.


80/8 = 10

Problem 2

A field is rectangular, the length of the field is 10 meters and the total area is 80 square meters. Find the width?

Ray, the Boy Character from BrightChamps Saying "Let’s Begin"

8 meters.
 

Explanation

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


Area = length × width


80 = 10 × width


To find the value of width, we need to shift 10 to the left side.


80/10 = width


Width = 8.
