Multiples of 80
In math, multiples are the products we get while multiplying a number with other numbers. Multiples play a key role in construction and design, counting groups of items, sharing resources equally, and managing time effectively. In this topic, we will learn the essential concepts of multiples of 80.
What are the Multiples of 80?
Now, let us learn more about multiples of 80. Multiples of 80 are the numbers you get when you multiply 80 by any whole number, including zero. Each number has an infinite number of multiples, including a multiple of itself. In multiplication, a multiple of 80 can be denoted as 80 × n, where ‘n’ represents any whole number (0, 1, 2, 3,…). So, we can summarize that:
Multiple of a number = Number × Any whole number
For example, multiplying 80 × 1 will give us 80 as the product. Multiples of 80 will be larger or equal to 80.
List of First 20 Multiples of 80
Multiples of 80 include the products of 80 and an integer. Multiples of 80 are divisible by 80 evenly. The first few multiples of 80 are given below:
| TABLE OF 80 (1-10) | |
|---|---|
|
80 x 1 = 80 |
80 x 6 = 480 |
|
80 x 2 = 160 |
80 x 7 = 560 |
|
80 x 3 = 240 |
80 x 8 = 640 |
|
80 x 4 = 320 |
80 x 9 = 720 |
|
80 x 5 = 400 |

Operations with Multiples of 80
Understanding the multiples of 80 helps solve mathematical problems and boost our multiplication and division skills. When working with multiples of 80, we need to apply it to different mathematical operations such as addition, subtraction, multiplication, and division.
Sum of first 5 Multiples of 80:
80, 160, 240, 320, and 400 are the first five multiples of 80. When multiplying 80 from 1 to 5, we get these numbers as the products. So, the sum of these multiples is:
80 + 160 + 240 + 320 + 400 = 1200
When we add the first 5 multiples of 80, the answer will be 1200.
Subtraction of first 5 Multiples of 80:
While we do subtraction, it improves our comprehension of how the value decreases when each multiple is subtracted from the previous one. 80, 160, 240, 320, and 400 are the first five multiples of 80. So, let us calculate it as given below:
80 - 160 = -80
-80 - 240 = -320
-320 - 320 = -640
-640 - 400 = -1040
Hence, the result of subtracting the first 5 multiples of 80 is -1040.
Average of first 5 Multiples of 80:
To calculate the average, we need to identify the sum of the first 5 multiples of 80, and then divide it by the count, i.e., 5. Because there are 5 multiples presented in the calculation. Averaging helps us to understand the concepts of central tendencies and other values. We know the sum of the first 5 multiples of 80 is 1200.
80 + 160 + 240 + 320 + 400 = 1200
Next, divide the sum by 5:
1200 ÷ 5 = 24
240 is the average of the first 5 multiples of 80.
Product of First 5 Multiples of 80:
The product of given numbers is the result of multiplying all of them together. Here, the first 5 multiples of 80 include 80, 160, 240, 320, and 400. Now, the product of these numbers is:
80 × 160 × 240 × 320 × 400 = 7,864,320,000,000
The product of the first 5 multiples of 80 is 7,864,320,000,000.
Division of First 5 Multiples of 80:
While we perform division, we get to know how many times 80 can fit into each of the given multiples. 80, 160, 240, 320, and 400 are the first 5 multiples of 80.
80 ÷ 80 = 1
160 ÷ 80 = 2
240 ÷ 80 = 3
320 ÷ 80 = 4
400 ÷ 80 = 5
The results of dividing the first 5 multiples of 80 are: 1, 2, 3, 4, and 5.
Common Mistakes and How to Avoid Them in Multiples of 80
While working with multiples of 80, we make common mistakes. Identifying these errors and understanding how to avoid them can be helpful. Below are some frequent mistakes and tips to avoid them:
Mistake 1
Confusing Multiples with Factors
Sometimes, students get confused between the multiples and factors of 80. A simple trick to differentiate between the two is to remember that multiples are the products of multiplication, while factors are the divisors of the number. Multiples of 80 refer to the products we get while multiplying 80 with other numbers. For example, multiples of 80 include 0, 80, 160, 240, 320, 400, 480...
The factors of 80 are 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80. These numbers can divide 80 without any remainder.
Factors of 80:
80 ÷ 1 = 80
80 ÷ 2 = 40
80 ÷ 4 = 20
80 ÷ 5 = 16
80 ÷ 8 = 10
80 ÷ 10 = 8
80 ÷ 16 = 5
80 ÷ 20 = 4
80 ÷ 40 = 2
80 ÷ 80 = 1
Multiples of 80 Examples
Problem 1
Maya runs a community center where they organize art classes. Each class can accommodate 80 participants. If they conduct classes for 5 consecutive weeks, each week filled to capacity, how many participants will attend in total?
400 participants
Explanation
Each week, 80 participants attend. To find the total number of participants over 5 weeks, multiply the number of participants per week by the number of weeks.
Participants per week = 80
Number of weeks = 5
80 × 5 = 400
Therefore, a total of 400 participants will attend over the 5 weeks.
Problem 2
In a local library, the librarian arranges books in multiples of 80 on display tables. On the first table, there are 80 books, on the second, there are 160 books, and on the third, there are 240 books. How many books are displayed in total across all three tables?
480 books
Explanation
The books are arranged in multiples of 80. The first table has 80 books, the second has 160 books, and the third has 240 books. Add these to find the total:
80 + 160 + 240 = 480
Therefore, there are 480 books displayed in total.
Problem 3
A factory produces toy cars in batches. Each batch contains 80 toy cars. If the factory produces 6 batches in one day, how many toy cars are produced in a day?
480 toy cars
Explanation
Each batch contains 80 toy cars. To find the total number of toy cars produced in a day, multiply the number of toy cars per batch by the number of batches.
Toy cars per batch = 80
Number of batches = 6
80 × 6 = 480
Therefore, the factory produces 480 toy cars in a day.
Problem 4
In a school event, chairs are arranged in rows, with each row having 80 chairs. If there are 4 such rows, how many chairs are there in total?
320 chairs
Explanation
To find the total number of chairs, multiply the number of chairs per row by the number of rows.
Number of chairs per row = 80
Number of rows = 4
80 × 4 = 320
Therefore, there are 320 chairs in total.
Problem 5
During a conference, gift bags are distributed to attendees. Each gift bag contains 80 items. If 3 sessions of the conference distribute gift bags and each session has the same number of attendees, how many items are distributed in total?
240 items
Explanation
Each gift bag contains 80 items. To find the total number of items distributed, multiply the number of items per gift bag by the number of sessions.
Items per gift bag = 80
Number of sessions = 3
80 × 3 = 240
Therefore, a total of 240 items are distributed during the conference.
