Function to calculate the least common multiple of two numbers in JavaScript
The least common multiple, (LCM) of two integers a and b, is the smallest positive integer that is divisible by both a and b.
For example −
LCM of 4 and 6 is 12 because 12 is the smallest number that is exactly divisible by both 4 and 6.
We are required to write a JavaScript function that takes in two numbers, computes and returns the LCM of those numbers.
Example
Following is the code −
const num1 = 4;
const num2 = 6;
const findLCM = (num1, num2) => {
let hcf;
for (let i = 1; i <= num1 && i <= num2; i++) {
if( num1 % i == 0 && num2 % i == 0) {
hcf = i;
};
};
let lcm = (num1 * num2) / hcf;
return lcm;
};
console.log(findLCM(num1, num2));Output
Following is the output on console −
12
