Are you asking what the divisibility rule for 4 is?
===========
A number is divisible by 5 if it ends in a 0 or a 5
=====
There are two ways to test for divisibility by 4.
A number is divisible by 4 if it is divisible by 2 twice. That is, the factor you get when you factor a 2 out must also be divisible by 2.
Example... is 516 divisible by 4?
Well, is it divisible by 2? Yes, it is even. Factor that 2 out you get 258. Is 258 also divisible by 2? Yes, it too is even. Since it was divisible by 2 and the quotient was also divisible by 2 then the original was divisible by 4.
But, 4's have another rule that is simpler.
All you have to do is look at the smallest two digits: the ones and tens place. You can ignore anything in the hundreds place or up. If the ones and tens place form a number that is divisible by 4 then the whole number is also divisible by 4
Example: Is 52848474116 divisible by 4?
Just take the last two digits off and test them. 16. Is 16 divisible by 4? Yes, so that whole mess of a number is also.
