 » In simpler words you will be given k, l, m, n and d as inputs. now you need to count the numbers starting from 1 and ending at d, which are divisible by atleast one of k,l,m,n; Explanation of sample input 1 : here d=12, so you need to count numbers from 1,2,3,.....,12 which are divisible by atleast one of (1,2,3,4). You can observe that count = 12.

 » But why do we have to count like that , can you clearly explain how did you figure out why such an approach is required to be followed

 » why i divide by k,l,m,n??I could not understand.

 » Every k-th dragon got punched in the face with a frying pan..it means from 1-d if a number is divisible by k then it suffered moral or physical damage.....same thing in l , m , n th....if a number from 1-d is divisible by any of 4 number then that dragon will suffer moral or physical damage..... so just you have to find the count how many number are divisible by k/l/m/n from 1 to d...and that's the answer
