HCF of Two Numbers using Functions
Write a C++ Program to Calculate HCF of Two Numbers using Functions . Here’s simple C++ Program to Calculate HCF of Two Numbers using Functions in C++ Programming Language.
HIGHEST COMMON FACTOR (H.C.F)
- The HCF of two (or more) numbers is the largest number that divides evenly into both numbers.
- In other words the H.C.F is the largest of all the common factors.
- The common factors or of 12 and 18 are 1, 2, 3 and 6.
- The largest common factor is 6, so this is the H.C.F. of 12 and 18.
- It is very easy to find a H.C.F. of small numbers, like 6 and 9 (it is 3) or 8 and 4 (it is 4).
- The best way is to keep finding the factors of the smaller number, starting from the largest factor. The first factor of the smaller number that is also a factor of the larger number is a H.C.F.
Here is source code of the C++ Program to Calculate HCF of Two Numbers using Functions. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.
SOURCE CODE : :
/* C++ Program to Calculate HCF of Two Numbers using Functions */ #include<iostream> using namespace std; void gcd(int,int); int main() { int a,b; cout<<"Enter 1st number :: "; cin>>a; cout<<"\nEnter 2nd number :: "; cin>>b; gcd(a,b); return 0; } //function to calculate g.c.d void gcd(int a,int b) { int m,n; m=a; n=b; while(m!=n) { if(m>n) m=m-n; else n=n-m; } cout<<"\nH.C.F of [ "<<a<<" ] and [ "<<b<<" ] is :: "<<m<<"\n"; }
Output : :
/* C++ Program to Calculate HCF of Two Numbers using Functions */ Enter 1st number :: 12 Enter 2nd number :: 30 H.C.F of [ 12 ] and [ 30 ] is :: 6 Process returned 0
Above is the source code for C++ Program to Calculate HCF of Two Numbers using Functions which is successfully compiled and run on Windows System.The Output of the program is shown above .

Thanks for reading the post….
include<iostream>
using namespace std;
int hcf(int a, int b)
{
if (b == 0)
return a;
return hcf(b, a % b);
}
int main()
{
int a,b;
cout<<“Enter two numbers:\n”;
cin>>a>>b;
cout<<“HCF of “<<a<<” and “<<b<<” is “<<hcf(a, b)<<endl;
system(“pause”);
return 0;
}
plz make theme light
#include <iostream>
using namespace std;
int HCF_Func(int, int);
int main()
{
int a,b;
int result;
cout<<“give two number:”<<endl;
cin>>a>>b;
result= HCF_Func(a,b);
cout<<“result is: “<<result;
return 0;
}
int HCF_Func(int a, int b)
{
int devide= a-1;
int re1,re2;
for(; devide>=1; devide–)
{
re1=a%devide;
if( re1==0 )
{
re2=b%devide;
if( re2==0 )
{
break;
}
}
}
return devide;
}
the function should be before the main
