Javascript code to find HCF and LCM of three numbers

function hl(){

let hcf;
// take input
const number1 = prompt('Enter a first positive integer: ');
const number2 = prompt('Enter a second positive integer: ');
const number3 = prompt('Enter a third positive integer: ');

// looping from 1 to number1 and number2 and number3
for (let i = 1; i <= number1 && i <= number2 && i <= number3; i++) {

    // check if is factor of all three integers
    if( number1 % i == 0 && number2 % i == 0 && number3 % i == 0) {
        hcf = i;
    }
}


// display the hcf 
console.log(`HCF of ${number1} , ${number2} and ${number3} is ${hcf}.`);
}
