Calculate the number of students

The exam employee tries to distribute students evenly in the examination halls, if she knows that the number of students varies

Between 500 and 1000 and that:

1- If students are divided into two halls, one student remains without the hall

2- If students are distributed into three halls, one student remains without the hall

3- If students are distributed into four halls, one student will remain without the hall

4- If students are distributed into five halls, one student remains without the hall

5- If students are distributed into six halls, one student will be left without the hall

6- If students are divided into seven halls, no student will remain without the hall

Write a program that allows you to see the actual number of students.

Looks like an assignment to me.

You didn't mention name of programming language to be used.

They want to know if you know the mod operator in the language you are learning.

Here is a piece of code in C#
Int32 answer = 500;
for (Int32 start = answer; start < 1000; start++)
{
    answer = start;
    if (start % 2 == 1 && start % 3 == 1 && start % 4 == 1 && start % 5 == 1 && start % 6 == 1 && start % 7 == 0)
        break;
}
Console.WriteLine(answer);

i think 721 will be the answer ,
it is very clear that No of student is a mutiple of 7 , ( between 500 and 1000) , so clearly answer should be 721
static void Main(string[] args)
      {

          for (int x = 504; x <= 994;x=x+7 )
          {
              if (x % 2 == 1 && x % 3 == 1 && x % 4 == 1 && x % 5 == 1 && x % 6 == 1)
              {
                  Console.WriteLine(x);
              }
          }

              Console.ReadLine();


      }
startingPoint = 500+(7-((int)(500%7))
endPoint =1000-(int)(1000%7)
