5900f5271000cf542c51003a Problem 443: GCD sequence 5 302115 problem-443-gcd-sequence

--description--

Let g(n) be a sequence defined as follows: g(4) = 13, g(n) = g(n-1) + gcd(n, g(n-1)) for n > 4.

The first few values are:

n 4567891011121314151617181920... g(n) 1314161718272829303132333451545560...

You are given that g(1 000) = 2524 and g(1 000 000) = 2624152.

Find g(1015).

--hints--

euler443() should return 2744233049300770.

assert.strictEqual(euler443(), 2744233049300770);

--seed-contents--

function euler443() {

  return true;
