FORMULA

a(n) <= A001055(n). - David A. Corneth, Oct 21 2017

EXAMPLE

The factorizations of 12 are (2,2,3), (2,6), (3,4), and (12), which have three distinct sums 7, 8, and 12. Hence a(12) = 3. - Antti Karttunen, Oct 21 2017

The factorizations of 30 are (2,3,5), (2,15), (3,10), (5,6) and (30), which have the 5 distinct sums 10, 17, 13, 11 and 30. Hence a(30) = 5.
