--description--

Los factores primos de 13195 son 5,7,13 y 29.

Cual es el factor primo mas grande del number?

--hints--

largestPrimeFactor(2) debe devolver un número.

assert(typeof largestPrimeFactor(2) === 'number');

largestPrimeFactor(2) debe devolver 2.

assert.strictEqual(largestPrimeFactor(2), 2);

largestPrimeFactor(3) debe devolver 3.

assert.strictEqual(largestPrimeFactor(3), 3);

largestPrimeFactor(5) debe devolver 5.

assert.strictEqual(largestPrimeFactor(5), 5);

largestPrimeFactor(7) debe devolver 7.

assert.strictEqual(largestPrimeFactor(7), 7);

largestPrimeFactor(8) debe devolver 2.

assert.strictEqual(largestPrimeFactor(8), 2);

largestPrimeFactor(13195) debe devolver 29.

assert.strictEqual(largestPrimeFactor(13195), 29);

largestPrimeFactor(600851475143) debe devolver 6857.

assert.strictEqual(largestPrimeFactor(600851475143), 6857);

--seed--

--seed-contents--

function largestPrimeFactor(number) {

  return true;
}

largestPrimeFactor(13195);

--solutions--

const largestPrimeFactor = (number) => {
  let largestFactor = number;

  for (let i = 2; i <= Math.sqrt(largestFactor); i++) {
    if (!(largestFactor % i)) {
      let factor = largestFactor / i;
      let candidate = largestPrimeFactor(factor);

      return i > candidate ? i : candidate;
    }
  }

  return largestFactor;
}
