--description--

The binomial coefficient 10C3 = 120.

120 = 23 × 3 × 5 = 2 × 2 × 2 × 3 × 5, and 2 + 2 + 2 + 3 + 5 = 14.

So the sum of the terms in the prime factorisation of 10C3 is 14.

Find the sum of the terms in the prime factorisation of 20000000C15000000.

--hints--

euler231() should return 7526965179680.

assert.strictEqual(euler231(), 7526965179680);

function euler231() {

  return true;
}

euler231();
