Description

如果我们计算a2 mod 6为0≤a≤5，我们得到：0,1,4,3,4,1。

a2≡amod 6的最大值为4.让我们将M（n）称为a <n的最大值，使得a2≡a（mod n）。所以M（6）= 4。

找ΣM（n）为1≤n≤107。

Instructions

Tests

tests:
  - text: <code>euler407()</code>应该返回39782849136421。
    testString: assert.strictEqual(euler407(), 39782849136421);

Challenge Seed

function euler407() {
  // Good luck!
  return true;
}

euler407();
