Class Program
When the static void Main (string[] args)//c# declares an array, the square brackets ([]) must follow the type, not the identifier behind

This is the opposite of the C language.
int [] RG =//Initialize array
for (Int64 i = 1; i < int64.maxvalue; i++)//int64 value types represent values ranging from 9,223,372,036,854,775,808 to +9,223,372,036,854,775,807 The integer between.
int hit = 0;
int hit1 =-1;
int hit2 =-1;
for (int j = 0; (J < RG. Length) && (hit <=2); J + +)
if ((i% rg[j])! = 0)
if (hit = = 1)
Hit1 = j;
else if (hit = = 2)
Hit2 = j;

if (hit = = 2) && (HIT1+1==HIT2))
Console.WriteLine ("Found {0}", i);

Question 1: What are the criteria for this program?

A: This is checked online: The Int64 value type represents an integer value between 9,223,372,036,854,775,808 and +9,223,372,036,854,775,807.

As for the procedure, I can't read it very well.

Question 2: Does such a number exist? What is the minimum number that meets this condition?

A: I personally think it should exist.

Question 3: How long do you expect to be able to output the first result when running this program on a computer? The time is accurate to minutes (computer: Single core CPU 4.0G Hz, memory and hard disk resources are sufficient).

A: I think it's quite a long time, about five minutes.

Question 4: How can I improve the efficiency of this program on multi-core computers?

A: Do it in several categories at the same time
