Calculate LCM (LCD)

calculateLCM​

The calculateLCM function calculates the least common multiple (LCM), also known as the least common divisor (LCD), of multiple provided numbers.

Function Signature​

function calculateLCM(...numbers: Numeric[]): number;

Parameters​

  • numbers: A list of numbers or numeric strings for which the LCM/LCD is to be calculated.

Return Value​

  • Returns the LCM/LCD of the provided numbers.
  • If no valid numbers are provided, it returns 0.

Example Usage​

import { calculateLCM } from 'nhb-toolbox';

console.log(calculateLCM(12, 15, 18)); // 180
console.log(calculateLCM(5, 10));      // 10
console.log(calculateLCM(7));          // 7
console.log(calculateLCM());           // 0

Notes​

  • The function works by progressively finding the LCM of pairs of numbers using the _find2NumbersLCM function.
  • If no valid numbers are provided, it returns 0 as the LCM/LCD.
  • The LCM of a single number is the number itself.
  • Only integer values are considered valid for calculating LCM/LCD.

Aliases​

  • calculateLCD: Alias for calculateLCM.

Conclusion​

The calculateLCM function is useful for determining the least common multiple of multiple numbers, making it valuable in problems such as scheduling, fractions, and number theory.
