How to find the prime factors of a number in Node.js

Answer 1

function printPrimeFactor(n) {
    let div = 2;
    while (n !== 0) {
        if (n % div !== 0) {
            div = div + 1;
        }
        else {
            console.log(div);
            n = n / div;
            if (n == 1) {
                break;
            }
        }
    }
    console.log();
}
  
const n = 124;
            
printPrimeFactor(n); // 2 * 2 * 32
printPrimeFactor(1883); // 7 * 269 
printPrimeFactor(1862); // 2 * 7 * 7 * 19
