wrong output to find prime factor of number

what's wrong with this code .
here v= any input value.
if i input 24 as 'v' then i should get 2,2,3,2 as output, but i am getting 2,3,4 as output.
both above are factors of 24 but the one i am getting is not prime factors.

void factor (int v)
      {
      int i;
      for (i=2;i<=v;i++)
      {
          if (v%i==0)
          {
                   printf("\n%d",i);
                   v=v/i;
                   i=2;
          }
      }
