Test the divisibility of the following numbers by 5 :
(i) 4965 (ii) 23590 (iii) 35208 (iv) 723405 (v) 124684 (vi) 438750

Answer

To determine whether each of the given numbers is divisible by 5, we will follow the divisibility rule for 5. According to this rule, a number is divisible by 5 if its last digit is either 0 or 5.

Let's analyze each number step by step:

### Step 1: Check the last digit of 4965
- The last digit is **5**.
- Since the last digit is 5, **4965 is divisible by 5**.

### Step 2: Check the last digit of 23590
- The last digit is **0**.
- Since the last digit is 0, **23590 is divisible by 5**.

### Step 3: Check the last digit of 35208
- The last digit is **8**.
- Since the last digit is neither 0 nor 5, **35208 is not divisible by 5**.

### Step 4: Check the last digit of 723405
- The last digit is **5**.
- Since the last digit is 5, **723405 is divisible by 5**.

### Step 5: Check the last digit of 124684
- The last digit is **4**.
- Since the last digit is neither 0 nor 5, **124684 is not divisible by 5**.

### Step 6: Check the last digit of 438750
- The last digit is **0**.
- Since the last digit is 0, **438750 is divisible by 5**.

### Summary of Results:
1. **4965**: Divisible by 5
2. **23590**: Divisible by 5
3. **35208**: Not divisible by 5
4. **723405**: Divisible by 5
5. **124684**: Not divisible by 5
6. **438750**: Divisible by 5
