C Program to Find GCD of two Numbers Using For Loop

Problem :- Write a C Program to Find GCD ( greatest common divisor ) of two Numbers Using For Loop .

Logic :- In mathematics, the greatest common divisor (gcd) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For example, the gcd of 8 and 12 is 4.

The greatest common divisor is also known as the greatest common factor (gcf), highest common factor (hcf),greatest common measure (gcm),or highest common divisor wikipedia

Solution :-

#include

int main()

{

  //GHANENDRA YADAV

    int num1, num2, i, hcf;

    

printf("Enter Two Integers :\n");

    scanf("%d %d", &num1, &num2);

    

for(i=1; i<=num1 || i<=num2; ++i)

    {

        if(num1%i==0 && num2%i==0)

            hcf=i;

    }

    printf("H.C.F of %d and %d is %d", num1, num2, hcf);

    return 0;

}

Output:-
