# --description--
考虑数字54. 54可以用7种不同的方式分解为大于154,2×27,3×18,6×9,3×3×6,2×3×9和2×的一个或多个因子3×3×3。如果我们要求所有因子都是无平方的则只剩下两种方式3×3×6和2×3×3×3。
让我们调用Fsfnn可以计算为一个或多个大于1的无平方因子的方式的数量因此Fsf54= 2。
对于k = 2到n令Sn为ΣFsfk
S100= 193。
找到S10 000 000 000
# --hints--
`euler362()`应该返回457895958010。
```js
assert.strictEqual(euler362(), 457895958010);
```

## --seed-contents--
```js
function euler362() {
return true;
}
euler362();
```
# --solutions--
```js
// solution required
