# --description--
|
||
|
||
令S（n，m）= ∑φ（n×i）且1≤i≤m。 （φ是欧拉的上位函数）
|
||
|
||
给出S（510510,106）= 45480596821125120。
|
||
|
||
找出S（510510,1011）。 输入答案的最后9位数字。
|
||
|
||
# --hints--
|
||
|
||
`euler432()`应该返回754862080。
|
||
|
||
```js
|
||
assert.strictEqual(euler432(), 754862080);
|
||
```
|
||
|
||
# --seed--
|

return true;
|

|
||
euler432();
