Find all numbers between an interval, divisible by a specific number

Posted on Apr 8, 2020

C program to find all numbers between an interval, divisible by a specific number, where range for interval and number is entered by user.

Program

#include<stdio.h>
#include<conio.h>
void main()
{
	int num1, num2, n;
    int i;

    printf("Enter two integers (interval)\t:");
    scanf("%d%d",&num1,&num2);
    printf("Enter the number by which divisibility is to be checked\t:");
    scanf("%d",&n);

    printf("\nNumbers between %d and %d, divisible by %d are \n",num1,num2,n);
    for(i=num1;i<=num2;i++)
    {
        if(i%n==0)
        {
            printf("%d, ",i);
        }
    }
    
    getch();
}

Output

Enter two integers (interval)   :25
250
Enter the number by which divisibility is to be checked :24

Numbers between 25 and 250, divisible by 24 are
48, 72, 96, 120, 144, 168, 192, 216, 240,
