c-program calculate the hcf and lcm of two numbers| c-programming languages

program calculate the hcf and lcm of two number in c-programming.

In this program , we will calculate the hcf and lcm of two numbers in c-program taking two inputs from the user .

 In this program, we first calculate the hcf and with the hcf calculate the lcm of two numbers.

 

#include<Stdio.h>
#include<conio.h>
void main()
{
    int a,b,h,l,i,lcm;
    printf("enter the two number ");
    scanf("%d %d",&a,&b);
    l=a<b?a:b;
    for(i=l;i>=1;i--)
        if(a%i==0&&b%i==0)
         break;
    printf("the hcf of the number is %d",i);
    lcm=(a*b)/i;
    printf("\nhe lcm of the number is %d",lcm);
    getch();
}

output:

              enters two numbers:

               a=12  and b=16

               hcf=4        and   lcm=48
