Examples

			A285487(1) = 1,    hence a(1)    = 1.
A285487(2) = 2310, hence a(2310) = 2.
A285487(3) = 2,    hence a(2)    = 3.
A285487(4) = 1155, hence a(1155) = 4.
A285487(5) = 4,    hence a(4)    = 5.
A285487(6) = 1365, hence a(1365) = 6.
A285487(7) = 6,    hence a(6)    = 7.
A285487(8) = 385,  hence a(385)  = 8.
