+# --description--
+
+Let $S(n, m) = \sum φ(n × i)$ for $1 ≤ i ≤ m$. ($φ$ is Euler's totient function)
+
+You are given that $S(510\\,510, {10}^6) = 45\\,480\\,596\\,821\\,125\\,120$.
+
+Find $S(510\\,510, {10}^{11})$. Give the last 9 digits of your answer.
+
+# --hints--
+
+`totientSum()` should return `754862080`.
+
+```js
+assert.strictEqual(totientSum(), 754862080);
+```
