Write the first five multiples of each of the following numbers .
(i) 17 , (ii) 23, (iii) 65, (iv) 70

Answer

To find the first five multiples of the given numbers (17, 23, 65, and 70), we will multiply each number by the integers 1 through 5.

### Step-by-Step Solution:

#### (i) First five multiples of 17:
1. **Multiply 17 by 1**:
- \( 17 \times 1 = 17 \)
2. **Multiply 17 by 2**:
- \( 17 \times 2 = 34 \)
3. **Multiply 17 by 3**:
- \( 17 \times 3 = 51 \)
4. **Multiply 17 by 4**:
- \( 17 \times 4 = 68 \)
5. **Multiply 17 by 5**:
- \( 17 \times 5 = 85 \)

**First five multiples of 17**: 17, 34, 51, 68, 85.

#### (ii) First five multiples of 23:
1. **Multiply 23 by 1**:
- \( 23 \times 1 = 23 \)
2. **Multiply 23 by 2**:
- \( 23 \times 2 = 46 \)
3. **Multiply 23 by 3**:
- \( 23 \times 3 = 69 \)
4. **Multiply 23 by 4**:
- \( 23 \times 4 = 92 \)
5. **Multiply 23 by 5**:
- \( 23 \times 5 = 115 \)

**First five multiples of 23**: 23, 46, 69, 92, 115.

#### (iii) First five multiples of 65:
1. **Multiply 65 by 1**:
- \( 65 \times 1 = 65 \)
2. **Multiply 65 by 2**:
- \( 65 \times 2 = 130 \)
3. **Multiply 65 by 3**:
- \( 65 \times 3 = 195 \)
4. **Multiply 65 by 4**:
- \( 65 \times 4 = 260 \)
5. **Multiply 65 by 5**:
- \( 65 \times 5 = 325 \)

**First five multiples of 65**: 65, 130, 195, 260, 325.

#### (iv) First five multiples of 70:
1. **Multiply 70 by 1**:
- \( 70 \times 1 = 70 \)
2. **Multiply 70 by 2**:
- \( 70 \times 2 = 140 \)
3. **Multiply 70 by 3**:
- \( 70 \times 3 = 210 \)
4. **Multiply 70 by 4**:
- \( 70 \times 4 = 280 \)
5. **Multiply 70 by 5**:
- \( 70 \times 5 = 350 \)

**First five multiples of 70**: 70, 140, 210, 280, 350.

### Final Answer:
- **Multiples of 17**: 17, 34, 51, 68, 85
- **Multiples of 23**: 23, 46, 69, 92, 115
- **Multiples of 65**: 65, 130, 195, 260, 325
- **Multiples of 70**: 70, 140, 210, 280, 350
