--description--

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 250?

--hints--

euler193() should return 684465067343069.

assert.strictEqual(euler193(), 684465067343069);

function euler193() {

  return true;
}

euler193();
