# --description--
令Snm= ∑φn×i且1≤i≤m。 (φ是欧拉的上位函数)
Let S(n,m) = ∑φ(n × i) for 1 ≤ i ≤ m. (φ is Euler's totient function)
给出S510510,106= 45480596821125120
You are given that S(510510,106 )= 45480596821125120.
找出S510510,1011)。 输入答案的最后9位数字。
Find S(510510,1011). Give the last 9 digits of your answer.

`euler432()`应该返回754862080
`euler432()` should return 754862080.
```js
assert.strictEqual(euler432(), 754862080);
