5900f4531000cf542c50ff66	5	false	Problem 231: The prime factorisation of binomial coefficients	301875

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.
