Before starting this article, I would like to ask if you still remember what is the greatest common divisor? In fact, it refers to the largest common divisor of two or more integers. So today I will introduce to you how to calculate the greatest common divisor through a javascript program.
However, I still want to introduce the simple concept of the greatest common divisor here:
→The greatest common factor, also known as the greatest common divisor, is also called the greatest common divisor. The greatest common factor is the largest divisor shared by two or more integers. For example, the greatest common divisor of a and b is recorded as (a, b). Similarly, the greatest common divisor of a, b, c is recorded as (a, b, c). Then the greatest common divisor of multiple integers is also Same mark. In fact, there are many methods to find the greatest common divisor. Common ones include prime factorization method, short division method, euclidean division method and phase-changing subtraction method. The concept corresponding to the greatest common divisor is the least common multiple. The least common multiple of a and b is recorded as [a, b] (I won’t go into too much introduction here).
Let’s get straight to the point.
The specific question is: Please write a JavaScript program to calculate the greatest common divisor of two positive integers.
Then we go directly to the code:
<!DOCTYPE HTML>
<html>
<head>
<script>
var a = 2154;
var b = 458;
var gcd;
while (a!=b)
{
if (a>b)
{
a = a -b;
}
else
{
b = b - a;
}
}
gcd = a;
console.log(gcd);
</script>
</head>
<body>
</body>
</html>The result is:
In the above code, we randomly gave two positive integers, They are 2154 and 458 respectively. It is obvious that the two greatest common divisors are 2.
Of course, replace it with another more obvious number:
var a = 25;
var b = 75;
var gcd;
while (a!=b)
{
if (a>b)
{
a = a -b;
}
else
{
b = b - a;
}
}
gcd = a;
console.log(gcd);Output:
The greatest common divisor of 25 and 75 is 25.
Finally, I would like to recommend "JavaScript Basics Tutorial" ~ Welcome everyone to learn ~

js中new操作符做了哪些事情Nov 13, 2023 pm 04:05 PMjs中new操作符做了：1、创建一个空对象，这个新对象将成为函数的实例；2、将新对象的原型链接到构造函数的原型对象，这样新对象就可以访问构造函数原型对象中定义的属性和方法；3、将构造函数的作用域赋给新对象，这样新对象就可以通过this关键字来引用构造函数中的属性和方法；4、执行构造函数中的代码，构造函数中的代码将用于初始化新对象的属性和方法；5、如果构造函数中没有返回等等。
