# --description--
For a positive integer n, define f(n) as the least positive multiple of n that, written in base 10, uses only digits ≤ 2.
Thus f(2)=2, f(3)=12, f(7)=21, f(42)=210, f(89)=1121222.
Also, .
Find .
# --hints--
`euler303()` should return 1111981904675169.
```js
assert.strictEqual(euler303(), 1111981904675169);
```
# --seed--
## --seed-contents--
```js
function euler303() {
return true;
}
euler303();
```
# --solutions--
```js
// solution required
```
