# --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）
|
||
|
||
# --hints--
|

|
||
`euler446()`应该返回907803852。
|
||
|
||
```js
|
||
assert.strictEqual(euler446(), 907803852);
|
||
```
