# --description--

n,rad(n)的基数是n的不同素因子的乘积。例如,504 = 23×32×7,因此rad(504)= 2×3×7 = 42.如果出现以下情况,我们将正整数(a,b,c)的三元组定义为abc-hit:GCD( a,b)= GCD(a,c)= GCD(b,c)= 1 a <ba + b = c rad(abc)<c例如,(5,27,32)是abc-hit,因为:GCD(5,27)= GCD(5,32)= GCD(27,32)= 1 5 <27 5 + 27 = 32 rad(4320)= 30 <32事实证明abc-hits是非常罕见的c <1000只有31次abc命中,Σc= 12523。查找Σc表示c <120000。

`euler127()`应该返回18407904。
|
||
|
||
```js
|
||
assert.strictEqual(euler127(), 18407904);
|
||
```
