Test the divisibility of the following numbers by 4 :
(i) 618 (ii) 2314 (iii) 63712 (iv) 35056 (v) 946126 (vi) 810524

Answer

To test the divisibility of the given numbers by 4, we will follow the rule that states: **A number is divisible by 4 if the number formed by its last two digits is divisible by 4.**

Let's go through each number step by step:

### Step 1: Check the number 618
- **Last two digits:** 18
- **Divisibility check:** 18 ÷ 4 = 4.5 (not an integer)
- **Conclusion:** 618 is **not divisible** by 4.

### Step 2: Check the number 2314
- **Last two digits:** 14
- **Divisibility check:** 14 ÷ 4 = 3.5 (not an integer)
- **Conclusion:** 2314 is **not divisible** by 4.

### Step 3: Check the number 63712
- **Last two digits:** 12
- **Divisibility check:** 12 ÷ 4 = 3 (an integer)
- **Conclusion:** 63712 is **divisible** by 4.

### Step 4: Check the number 35056
- **Last two digits:** 56
- **Divisibility check:** 56 ÷ 4 = 14 (an integer)
- **Conclusion:** 35056 is **divisible** by 4.

### Step 5: Check the number 946126
- **Last two digits:** 26
- **Divisibility check:** 26 ÷ 4 = 6.5 (not an integer)
- **Conclusion:** 946126 is **not divisible** by 4.

### Step 6: Check the number 810524
- **Last two digits:** 24
- **Divisibility check:** 24 ÷ 4 = 6 (an integer)
- **Conclusion:** 810524 is **divisible** by 4.

### Summary of Results:
- 618: Not divisible by 4
- 2314: Not divisible by 4
- 63712: Divisible by 4
- 35056: Divisible by 4
- 946126: Not divisible by 4
- 810524: Divisible by 4
