C program to calculate the GCD of a number

Write a program to calculate the Greatest Common Divisor(GCD) of a number #include<stdio.h> #include<conio.h> #include<process.h> int gcd(int m,int n) { int rem; while(n!=0) { rem=m%n; m=n; n=rem; } return(m); } main() { int num1,num2,num3,gcd1,gcd2; clrscr(); printf("Enter three positive integers"); scanf("%d%d%d",&num1,&num2,&num3); if(num1==0 && num2==0 && num3==0) { printf("\n Invalid number"); exit(0); } gcd1=gcd(num1,num2); gcd2=gcd(num3,gcd1); printf("\n GCD […]
