WebJul 8, 2016 · We can have at most four different prime divisors, as you said,because otherwise n > 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310. Also, we may assume that we have the smallest primes, i.e., n = 2 e 1 3 e 2 5 e 3 7 e 4 . So your method works well, and we obtain, after only cheking a few cases, d ( 1680) = d ( 2 4 ⋅ 3 ⋅ 5 ⋅ 7) = 5 ⋅ 2 ⋅ 2 ⋅ 2 = 40 as the maximum.
