Example & Tutorial understanding programming in easy ways.

Write a program to find the LCM of the two number

LCM:
Stand for Lowest common multiple

Example-
LCM of 5 and 6 is 30
LCM of 4 and 6 is 12
LCM of 10 and 30 is 30


program-

#include< stdio.h>
int main() {
int i,n1,n2,max;
printf("Enter first number");
scanf("%d",&n1);
printf("Enter second number");
scanf("%d",&n2);
if(n1>n2)
max=n1;
else
max=n2;
for(i=max;i< =n1*n2;i++)
{
if(i%n1==0 && i%n2==0)
{
printf("LCM is %d",i);
break;
}
}
}

output-

Enter first number
5
Enter second number
15
LCM is 15

Enter first number
5
Enter second number
6
LCM is 30

-In this program, we take an input of two integer number and try to find there LCM.
-We run loop starting from largest number to multiply of both number.
-In between, if any value that is divisible by both, then it is considered as LCM of both number so we break the loop and display the LCM.
