Problem Statement for LCM:
Enter Two digits by a user and get its LCM
Answer:
#include
#include
void main()
{
int x,y,i,j;
clrscr();
printf("Enter Two Digits");
scanf("d",&x,&y);
for(i=1;i<=x;i++)
{
for(j=1;j<=y;j++)
{
if(y*i==x*j)
{
printf("LCM is %d\n",y*i);
i=i+x;
}
}
}
getch();
}
OR
there will be another easy way to solve it...
Answer:
#include
#include
void main()
{
int x,y,i,;
clrscr();
printf("Enter Two Digits = ");
scanf("d",&x,&y);
for(i=1;i<=x*y;i++) {
if(i%x==0&&i%y==0)
{
printf(LCM is %d",i);
break;
}
}
getch();
}

DevinHey Friends here is the program of HCF and LCM with output:
Statement of C Program: Find The LCM and HCF of Two Numbers :
#include
void main()
{
int num1 , num2 , lcm , gcd , remainder , numerator , denominator ;
clrscr();
printf( "Enter two numbers\n");
scanf(" %d%d " , &num1 , &num2 );
if (num1 > num2)
{
numerator=num1;
denominator=num2;
}
else
{
numerator = num2 ;
denominator = num1 ;
}
remainder = num1 % num2;
while ( remainder != 0)
{
numerator = denominator;
denominator = remainder;
remainder = numerator % denominator;
}
gcd = denominator;
lcm = (num1 * num2 ) / gcd;
printf("GCD of %d and %d =%d\n" , num1, num2, gcd);
printf(" LCM of %d and %d= %d\n" , num1, num2, lcm);
getch();
}
Output:
Enter two numbers
5
15
GCD of 5 and 15 = 5
LCM of 5 and 15 = 15

Write a program that will graph using for loop?
A = 5do{statement;A = A + 1;} while (A < 10)
Using while loop write a program which calculates the product of digits from 1 to 5 and also show these nos vertically?

How do you loop a program in python 3?
A program can be looped in Python by wrapping the entire program in a for or while loop. If you wish to loop the program a finite amount of times, it can be done like so (x = the amount of times you want it to loop, this can be a number or variable storing a number): for i in range(0,x): [code] If you wish to loop the program infinitely, you can use a simple while loop: while True: [code]
C program to find square of number using do while loop?

What are the disadvantages of the While Loop?
With loops, your program is slower.
