A number is divisible by 4 if the last two digits form a number that is divisible by 4, e.g. 312 is divisible by 4 (because 12 is divisible by 4).

You can tell if the last 2 digits of the number can be divisible by 4 or 8. So the number 3156372856374856386578365864would be divisible by 8 because 8 can go into 64.

Get the last two digits of the number. If that number is divisible by 4 then that number is divisible by 4. Example : 2393844 The last two digits are 44 and since 44/4 = 11 or 44 is divisible by 4 then the number 2,393,844 is divisible by 4.

If the last two digits of a number are divisible by 4, the whole number is divisible by 4.

No. If the last two digits of a number are divisible by 4, then the whole number is divisible by 4. So, 34 is not divisible by 4, therefore 634 is not divisible by 4.
