# --description--
|
||
|
||
数为n的unit除数d是n的除数，其性质为gcd（d，n / d）= 1。
|
||
|
||
4的除数！ = 24是1、3、8和24。
|
||
|
||
它们的平方和是12 + 32 + 82 + 242 = 650。
|
||
|
||
令S（n）表示n的一元除数的平方和。 因此，S（4！）＝ 650。
|
||
|
||
求S（100000000！）取模1000000009。

`euler429()`应该返回98792821。
|
||
|
||
```js
|
||
assert.strictEqual(euler429(), 98792821);
|
||
```
