给定 LCM 和 HCF 时找到另一个数字
原文:https://www . geeksforgeeks . org/find-the-other-number-when-LCM-and-hcf-given/
给定一个数字 A 和 L.C.M 和 H.C.F. 任务是确定另一个数字 B. 示例:
Input: A = 10, Lcm = 10, Hcf = 50.
Output: B = 50
Input: A = 5, Lcm = 25, Hcf = 4.
Output: B = 20
公式:-
A * B = LCM * HCF B =(LCM * HCF)/A 例:A = 15，B = 12 HCF = 3，LCM = 60 我们可以看到 3 * 60 = 15 * 12。 这个公式是怎么用的？ 既然 HCF 把两个数都除了，那就让。 A = HCF * x B = HCF * y 注意 x 和 y 不是共同的因素，所以 LCM 必须包含 HCF、x 和 y 这样就可以得出结论。 LCM = HCF * x * y 所以 LCM * HCF = HCF * x * y * HCF 等于 A * B
以下是上述方法的实现:
C++
// CPP program to find other number from given
// HCF and LCM
#include <bits/stdc++.h>
using namespace std;
// Function that will calculates
// the zeroes at the end
int otherNumber(int A, int Lcm, int Hcf)
{
return (Lcm * Hcf) / A;
}
// Driver code
int main()
{
int A = 8, Lcm = 8, Hcf = 1;
// Calling function.
int result = otherNumber(A, Lcm, Hcf);
cout << "B = " << result;
return 0;
}
Java 语言(一种计算机语言，尤用于创建网站)
// Java program to find other number from given
// HCF and LCM
class GFG{
// Function that will calculates
// the zeroes at the end
static int otherNumber(int A, int Lcm, int Hcf)
{
return (Lcm * Hcf) / A;
}
// Driver code
public static void main(String args[])
{
int A = 8, Lcm = 8, Hcf = 1;
// Calling function.
int result = otherNumber(A, Lcm, Hcf);
System.out.println("B = "+ result);
}
}
Python 3
# Python 3 program to find other
# number from given HCF and LCM
# Function that will calculates
# the zeroes at the end
def otherNumber(a, Lcm, Hcf):
return (Lcm * Hcf) // A
# Driver code
A = 8; Lcm = 8; Hcf = 1
# Calling function
result = otherNumber(A, Lcm, Hcf)
print("B =", result)

C
// C# program to find other number

using System;
class GFG
{
// Function that will calculates
// the zeroes at the end
static int otherNumber(int A, int Lcm,
int Hcf)
{
return (Lcm * Hcf) / A;
}
// Driver code
static public void Main(String []args)
{
int A = 8, Lcm = 8, Hcf = 1;
// Calling function.
int result = otherNumber(A, Lcm, Hcf);
Console.WriteLine("B = " + result);
}
}

<?php
// PHP program to find other number
// from given HCF and LCM
// Function that will calculates
// the zeroes at the end
function otherNumber($A, $Lcm, $Hcf)
{
return ($Lcm * $Hcf) / $A;
}
// Driver code
$A = 8; $Lcm = 8; $Hcf = 1;
// Calling function.
$result = otherNumber($A, $Lcm, $Hcf);
echo "B = " . $result;
