>>28016261912 is evenly splittable into 1, 2, 3, 4, 6, 12, or rather, wholes, halves, thirds, quarters, sixths, twelfths
10 on the other hand is only splittable into 1, 2, 5,10 or rather, wholes, halves, fifths, tenths
10 can not evenly split into thirds or quarters which makes it more obtuse to deal with at a glance compared to 12
same with 60, it's more evenly splittable than 100, and also because it's a factor of 12
