# --description--
|
||
|
||
The first number $n$ for which $φ(n) = 13!$ is $6\\,227\\,180\\,929$.
|
||
|
||
Find the ${150\\,000}^{\text{th}}$ such number.
|
||
|
||
# --hints--
|
||
|
||
`eulersTotientFunctionEquals()` should return `23507044290`.
|
||
|
||
```js
|
||
assert.strictEqual(eulersTotientFunctionEquals(), 23507044290);
|
||
```
