# --description--
Il coefficiente binomiale $\displaystyle\binom{10}{3} = 120$.
$120 = 2^3 × 3 × 5 = 2 × 2 × 2 × 3 × 5$, e $2 + 2 + 2 + 3 + 5 = 14$.
Quindi la somma dei termini nella fattorizzazione prima di $\displaystyle\binom{10}{3}$ è $14$.
Trova la somma dei termini nella fattorizzazione prima di $\binom{20\\,000\\,000}{15\\,000\\,000}$.
# --hints--
`primeFactorisation()` dovrebbe restituire `7526965179680`.
```js
assert.strictEqual(primeFactorisation(), 7526965179680);
```
# --seed--
## --seed-contents--
```js
function primeFactorisation() {
return true;
}
primeFactorisation();
```
# --solutions--
```js
// solution required
```
