C max of sums - need to modify it to stop adding the sums -

this program needs let users enter numbers , calculate sum of factors each entered number.

it needs until user enters number odd , dividable 5 (it not calculate sum of last number). , needs list number of sums calculated , biggest sum.

the problem i'm having program , instead of showing biggest sum (max) shows sums of sums.

suma sum variable

#include <stdio.h> #include <stdlib.h> main() { int x ,i ,suma=0 ,nr=0 ,max=0;    while(1) { printf("introduceti un intreg:\n"); scanf("%d",&x);  for(i=2;i<=x/2;i++)      //the checks if factor of x, adds                           //sum of factors { if(x%i==0)           suma = suma + i; }  if (x%2!=0 && x%5==0)           break;           nr++;  if (suma>=max)           max=suma;   }  printf("numarul sumelor calculate este %d\n\n",nr);     //the number of sums calculated printf("suma este : %d",max);                           //the maximum sum   } 

suma should initialized before for loop (so re-initialized each sum), not @ stop of program.
