A positive integer n is called squarefree, if no square of a prime divides n, thus 1, 2, 3, 5, 6, 7, 10, 11 are squarefree, but not 4, 8, 9, 12.

How many squarefree numbers are there below 2^{50}?

--hints--

squarefreeNumbers() should return 684465067343069.

assert.strictEqual(squarefreeNumbers(), 684465067343069);

function squarefreeNumbers() {

  return true;
}

squarefreeNumbers();
