### Worked Examples on Multiples

Make use of the properties of multiples such as Every number is multiple in itself, Every multiple of a number is either greater than or equal to the number, Every number is a multiple of 1, etc to solve the problems given below.

**Example 1.**

Write first five multiples of 10.

**Solution:**

The first five multiples of 10 are

10 × 1 = 10

10 × 2 = 20

10 × 3 = 30

10 × 4 = 40

10 × 5 = 50

Therefore the first five multiples of 10 are 10, 20, 30, 40, 50.

**Example 2.**

Write the first three multiples of 14.

**Solution:**

The first three multiples of 14 are

14 × 1 = 14

14 × 2 = 28

14 × 3 = 42

Therefore the first three multiples of 14 are 14, 28 and 42.

**Example 3.**

Write the first 5 common multiples of 3 and 6.

**Solution:**

M(3) = {3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 41, 44….}

M(6) = {6, 12, 18, 24, 30, 36, 42, 48, 54, 60….}

From the above multiples we can write the first 5 common multiples of 3 and 6 as 6, 12, 18, 24, 30.

**Example 4.**

Write first five multiples of

i. 21 ii. 13 iii. 17 iv. 18 v. 4

**Solution:**

**i. 21**

The first five multiples of 21 are

21 × 1 = 21

21 × 2 = 42

21 × 3 = 63

21 × 4 = 84

21 × 5 = 105

Therefore the first five multiples of 21 are 21, 42, 63, 84, 105.

**ii. 13**

The first five multiples of 13 are

13 × 1 = 13

13 × 2 = 26

13 × 3 = 39

13 × 4 = 52

13 × 5 = 65

Therefore the first five multiples of 13 are 13, 26, 39, 52, 35.

**iii. 17**

The first five multiples of 17 are

17 × 1 = 17

17 × 2 = 34

17 × 3 = 51

17 × 4 = 68

17 × 5 = 85

Therefore the first five multiples of 17 are 17, 34, 51, 68, 85.

**iv. 18**

The first five multiples of 18 are

18 × 1 = 18

18 × 2 = 36

18 × 3 = 54

18 × 4 = 72

18 × 5 = 90

Therefore the first five multiples of 18 are 18, 36, 54, 72, 90.

**v. 4**

The first five multiples of 4 are

4 × 1 = 4

4 × 2 = 8

4 × 3 = 12

4 × 4 = 16

4 × 5 = 20

Therefore the first five multiples of 4 are 4, 8, 12, 16, 20.

**Example 5.**

Find the common multiples of 4 and 12.

**Solution:**

A common multiple is a multiple that two or more numbers having a common number.

Multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48….

Multiples of 12 are 12, 24, 36, 48, 60, 72, 84,…

Thus the common multiples of 4 and 12 are 12, 24, 36, 48.

**Example 6.**

Write three common multiples of 6 and 8.

**Solution:**

A common multiple is a multiple that two or more numbers having a common number.

Multiples of 6 are 6, 12, 18, 24, 30, 36, 42, 48,…

Multiples of 8 are 8, 16, 24, 32, 40, 48,….

Thus the common multiples of 6 and 8 are 24, 48.

**Example 7.**

Prove that every number is multiple in itself.

**Solution:**

Let us solve some problems to prove that every number is multiple in itself.

22 × 1 = 22

4656 × 1 = 4656

9 × 1 = 9

59 × 1 = 59

By writing this product we can say that any number multiplied by 1 will be always the same number.

**Example 8.**

Write the first ten multiples of 7

**Solution:**

The first ten multiples of 7 are

7 × 1 = 7

7 × 2 = 14

7 × 3 = 21

7 × 4 = 28

7 × 5 = 35

7 × 6 = 42

7 × 7 = 49

7 × 8 = 56

7 × 9 = 63

7 × 10 = 70

Thus the first 10 multiples of 7 are 7, 14, 21, 28, 35, 42, 49, 56, 63, 70.

M(7) = {7, 14, 21, 28, 35, 42, 49, 56, 63, 70}

**Example 9.**

The numbers which are multiples of 2 are called ________

**Solution:**

The multiples of 2 are 2, 4, 6, 8, 10, 12, 14,….
