Which of the following number is exactly divisible by 2, 3 and 8?

Correct option is A

Given
Numbers: 34800, 43888, 34810, 42316
Divisors: 2, 3, 8

Formula Used
Divisibility rule of 3: Sum of digits must be divisible by 3.
Divisibility rule of 8: Last three digits must be divisible by 8.

Solution
If a number is divisible by 8, it is automatically divisible by 2.

Let us check option (A) 34800:

Last three digits are 800, which is exactly divisible by 8.

Sum of digits = 3 + 4 + 8 + 0 + 0 = 15, which is divisible by 3.

Since 34800 is divisible by both 3 and 8, it is exactly divisible by 2, 3, and 8.

So the correct answer is (a)
