2,4,6,8,and 0 are divisible by 2 in the ones digit. Zero is only divisible in a number with 2 digits or more. 0 itself is not divisible by 2.
To find a number with 8 in the hundreds place, think about what the hundreds place means. In a number like 832, the hundreds place is the third digit from the right. So, if a number has 8 in the hundreds place, it looks like 8 _ _, where the _ _ can be any digits. For example, 832 has 8 in the hundreds place. Another example is 854, or 879. In each of these numbers, 8 is in the hundreds place. So, any number between 800 and 899 has an 8 in the hundreds place.

It is assumed that the question requires each of the four digits to be used once and only once - ie permutations of {1, 2, 3, 4}. Since 100 is divisible by 4, any number of hundreds is divisible by 4. So the test of divisibility by 4 reduces to whether the last two digits are divisible by 4. For each pair of digits in the tens and units place that satisfy this requirement, the first two (thousands and hundreds) can be selected in two ways. So there are two numbers ending in 12 two ending in 24 and two ending in 32 six in all.
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 4Example: 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.
