Multiples of 20

Q: How do you find the multiples of 20?

To find out the multiples of 20, we need to multiply 20 by any natural number. Natural numbers include 1, 2, 3,...etc. The results will be multiples of 20. Multiples of 20 will be larger or equal to 20. 20 × 1 = 20 20 × 2 = 40 20 × 3 = 60 20 × 4 = 80 20 × 5 = 100

Q: What is the LCM of 15 and 20?

LCM of 15 and 20 is 60. LCM refers to the Least Common Multiple of two or more numbers. While we find out the LCM of 15 and 20 using the listing method, we need to list the multiples of both 15 and 20. Multiples of 15 are 15, 30, 45, 60, 75, 90,… Multiples of 20 are 20, 40, 60, 80, 100, 120,… Here, the smallest common number that appears in both lists is 60. LCM of 15 and 20 = 60.

Q: What are the real-life applications of Multiples of 20?

Multiples of 20 can be helpful in various real-life situations. We can use it for calculating the price of items, evaluating the value of multiple items, and organizing a number into groups.

Q: Are multiples of 20 finite or infinite?

All the multiples of 20 are infinite. In multiplication, every number has infinite multiples, including a multiple of itself. There are both positive and negative multiples of 20. When we calculate 20 × n, if the integer ‘n’ goes on forever, the multiples of 20 also become infinite.

Q: Is there any odd multiples of 20?

No, there are no odd numbers in the multiples of 20. Because 20 is an even number. If we multiply any even number by any number, we will get an even number as the product. For example, 20 × 1 = 20 20 × 2 = 40 20 × 3 = 60 20 × 4 = 80 20 × 5 = 100

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 20.

What are the Multiples of 20?

Now, let us learn more about multiples of 20. Multiples of 20 are the numbers you get when you multiply 20 by any whole number, including zero. Each number has an infinite number of multiples, including a multiple of itself. In multiplication, a multiple of 20 can be denoted as 20 × 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 20 × 1 will give us 20 as the product. Multiples of 20 will be larger or equal to 20. $Multiples of 20$

List of First 20 Multiples of 20

Multiples of 20 include the products of 20 and an integer. Multiples of 20 are divisible by 20 evenly. The first few multiples of 20 are given below:

TABLE OF 20 (1-10)
20 x 1 = 20	20 x 6 = 120
20 x 2 = 40	20 x 7 = 140
20 x 3 = 60	20 x 8 = 160
20 x 4 = 80	20 x 9 = 180
20 x 5 = 100	20 x 10 = 200

TABLE OF 20 (11-20)
20 x 11 = 220	20 x 16 = 320
20 x 12 = 240	20 x 17 = 340
20 x 13 = 260	20 x 18 = 360
20 x 14 = 280	20 x 19 = 380
20 x 15 = 300	20 x 20 = 400

Now, we know the first few multiples of 20. They are 0, 20, 40, 60, 80, 100, 120, 140, 160, 180, 200,...

Operations with Multiples of 20

Understanding the multiples of 20 helps solve mathematical problems and boosts our multiplication and division skills. When working with multiples of 20, we need to apply it to different mathematical operations such as addition, subtraction, multiplication, and division.

Sum of first 5 Multiples of 20:

20, 40, 60, 80, and 100 are the first five multiples of 20. When multiplying 20 from 1 to 5, we get these numbers as the products.
So, the sum of these multiples is:

20 + 40 + 60 + 80 + 100 = 300

When we add the first 5 multiples of 20, the answer will be 300.

Subtraction of first 5 Multiples of 20:

While we do subtraction, it improves our comprehension of how the value decreases when each multiple is subtracted from the previous one. 20, 40, 60, 80, and 100 are the first five multiples of 20. So, let us calculate it as given below:

20 - 40 = -20
-20 - 60 = -80
-80 - 80 = -160
-160 - 100 = -260

Hence, the result of subtracting the first 5 multiples of 20 is -260.

Average of first 5 Multiples of 20:

To calculate the average, we need to identify the sum of the first 5 multiples of 20, 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 20 is 300.

20 + 40 + 60 + 80 + 100 = 300

Next, divide the sum by 5:

300 ÷ 5 = 60

60 is the average of the first 5 multiples of 20.

Product of First 5 Multiples of 20:

The product of given numbers is the result of multiplying all of them together. Here, the first 5 multiples of 20 include: 20, 40, 60, 80, and 100. Now, the product of these numbers is:

20 × 40 × 60 × 80 × 100 = 38,400,000

The product of the first 5 multiples of 20 is 38,400,000.

Division of First 5 Multiples of 20:

While we perform division, we get to know how many times 20 can fit into each of the given multiples. 20, 40, 60, 80, and 100 are the first 5 multiples of 20.

20 ÷ 20 = 1
40 ÷ 20 = 2
60 ÷ 20 = 3
80 ÷ 20 = 4
100 ÷ 20 = 5

The results of dividing the first 5 multiples of 20 are: 1, 2, 3, 4, and 5.
