A simple C program to calculate the LCM (Lowest Common Multiple) of two integers using loops and decision making statements.
int n1, n2, minMultiple;
printf("Enter two positive integers: ");
scanf("%d %d", &n1, &n2);
// maximum number between n1 and n2 is stored in minMultiple
minMultiple = (n1>n2) ? n1 : n2;
// Always true
if( minMultiple%n1==0 && minMultiple%n2==0 )
printf("The LCM of %d and %d is %d.", n1, n2,minMultiple);
Enter two positive integers: 72
The LCM of 72 and 120 is 360.
