Today, We want to share with you **Golang to Find the GCD and LCM of Two Integers**.In this post we will show you **GO Program to Find the GCD and LCM of Two Integers**, hear for *Find GCD of Two Numbers Using Golang Recursion* we will give you demo and example for implement.In this post, we will learn about *GO program to find gcd of two numbers using recursion* with an example.

## Golang to Find the GCD and LCM of Two Integers

There are the Following The simple About **Golang to Find the GCD and LCM of Two Integers** Full Information With Example and source code.

As I will cover this Post with live Working example to develop **how to find gcd of two numbers using GO Program**, so the Program To Find HCF In GO for this example is following below.

Example of Switch in ….. Case GO Program to calculate the maths formula **LCM and GCD** of two any integers. The simple as well as used to For…Loop used as a While Loop in this Golang example below.

**Golang Program to find LCM and GCD of two numbers**

package main import "fmt" func lcm(first_tmp int,second_tmp int) { var lcmnum int =1 if(first_tmp>second_tmp) { lcmnum=first_tmp }else{ lcmnum=second_tmp } for { if(lcmnum%first_tmp==0 && lcmnum%second_tmp==0) { fmt.Printf("LCM of %d and %d is %d",first_tmp,second_tmp,lcmnum) break } lcmnum++ } return } func gcd(first_tmp int,second_tmp int){ var gcdnum int for i := 1; i <=first_tmp && i <=second_tmp ; i++ { if(first_tmp%i==0 && second_tmp%i==0) { gcdnum=i } } fmt.Printf("GCD of %d and %d is %d",first_tmp,second_tmp,gcdnum) return } func main() { var first_no,second_no,action int fmt.Println("Please Enter Your Any two positive integers : ") fmt.Scanln(&first_no) fmt.Scanln(&second_no) fmt.Println("Enter 1 for LCM and 2 for GCD") fmt.Scanln(&action) switch action { case 1: lcm(first_no,second_no) case 2: gcd(first_no,second_no) } }

here above Go Program Example To Use of Switch Case.
