Solve question 2 4th one

Dear student,
if a number is even then it is divisible by 2.
So,  6533142 is divisible by 2.
if the number formed by the last two digits in a number is divisible by 4, the original number is divisible by 4

clearly, 42 is not divisible by 4, so 6533142 is not divisible by 4.

If a number is not divisible by 4, it can not be divisible by 8.
So 6533142 is not divisible by 8.

Regards!
