Description

对于每个整数n> 1，函数族fn，a，b由fn，a，b（x）≡ax+ b mod n定义为a，b，x整数和0

对于1≤n≤N，F（N）=ΣR（n4 + 4）。 F（1024）= 77532377300600。

求F（107）（mod 1 000 000 007）

tests:
  - text: <code>euler446()</code>应该返回907803852。
    testString: assert.strictEqual(euler446(), 907803852);

function euler446() {
  // Good luck!
  return true;
}

euler446();

// solution required
