--description--

The first number n for which φ(n) = 13! is 6\\,227\\,180\\,929.

Find the {150\\,000}^{\text{th}} such number.

--hints--

eulersTotientFunctionEquals() should return 23507044290.

assert.strictEqual(eulersTotientFunctionEquals(), 23507044290);

--seed--

--seed-contents--

function eulersTotientFunctionEquals() {

  return true;
}

eulersTotientFunctionEquals();
