Advance Topics

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 30.

What are the Multiples of 30?

Now, let us learn more about multiples of 30. Multiples of 30 are the numbers you get when you multiply 30 by any whole number, including zero. Each number has an infinite number of multiples, including a multiple of itself. In multiplication, a multiple of 30 can be denoted as 30 × 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 30 × 1 will give us 30 as the product. Multiples of 30 will be larger or equal to 30.Multiples of 30

List of First 20 Multiples of 30

Multiples of 30 include the products of 30 and an integer. Multiples of 30 are divisible by 30 evenly. The first few multiples of 30 are given below:

 

TABLE OF 30 (1-10)

30 x 1 = 30

30 x 6 = 180

30 x 2 = 60

30 x 7 = 210

30 x 3 = 90

30 x 8 = 240

30 x 4 = 120

30 x 9 = 270

30 x 5 = 150

30 x 10 = 300

 

TABLE OF 30 (11-20)

30 x 11 = 330

30 x 16 = 480

30 x 12 = 360

30 x 17 = 510

30 x 13 = 390

30 x 18 = 540

30 x 14 = 420

30 x 19 = 570

30 x 15 = 450

30 x 20 = 600

 

Now, we know the first few multiples of 30. They are 0, 30, 60, 90, 120, 150, 180, 210, 240, 270, 300,...

Operations with Multiples of 30

Understanding the multiples of 30 helps solve mathematical problems and boosts our multiplication and division skills. When working with multiples of 30, we need to apply it to different mathematical operations such as addition, subtraction, multiplication, and division.

 

Sum of first 5 Multiples of 30:

 
30, 60, 90, 120, and 150 are the first five multiples of 30. When multiplying 30 from 1 to 5, we get these numbers as the products. So, the sum of these multiples is:  


30 + 60 + 90 + 120 + 150 = 450  


When we add the first 5 multiples of 30, the answer will be 450.

 

Subtraction of first 5 Multiples of 30: 


While we do subtraction, it improves our comprehension of how the value decreases when each multiple is subtracted from the previous one. 30, 60, 90, 120, and 150 are the first five multiples of 30. So, let us calculate it as given below:  


30 - 60 = -30  
-30 - 90 = -120  
-120 - 120 = -240  
-240 - 150 = -390  


Hence, the result of subtracting the first 5 multiples of 30 is -390.

 

Average of first 5 Multiples of 30:

 
To calculate the average, we need to identify the sum of the first 5 multiples of 30, and then divide it by the count, i.e., 5. Because there are 5 multiples presented in the calculation. Averaging helps us understand the concepts of central tendencies and other values. We know the sum of the first 5 multiples of 30 is 450.  


30 + 60 + 90 + 120 + 150 = 450  


Next, divide the sum by 5:  


450 ÷ 5 = 90  


90 is the average of the first 5 multiples of 30.

 

Product of First 5 Multiples of 30: 


The product of given numbers is the result of multiplying all of them together. Here, the first 5 multiples of 30 include: 30, 60, 90, 120, and 150. Now, the product of these numbers is:

 
30 × 60 × 90 × 120 × 150 = 29,160,000,000  


The product of the first 5 multiples of 30 is 29,160,000,000.

 

Division of First 5 Multiples of 30:  


While we perform division, we get to know how many times 30 can fit into each of the given multiples. 30, 60, 90, 120, and 150 are the first 5 multiples of 30.  


30 ÷ 30 = 1  
60 ÷ 30 = 2  
90 ÷ 30 = 3  
120 ÷ 30 = 4  
150 ÷ 30 = 5  


The results of dividing the first 5 multiples of 30 are: 1, 2, 3, 4, and 5.
