What odd number has 12 factors?

Answer 1

Well,there's one answer I know--9999!

9999 = 3^2 x 11 x 101 is indeed one.

But there are many smaller odd numbers.

315 = 3^2 x 5 x 7 is the smallest; the next five are

495 = 3^2 x 5 x 11

525 = 3 x 5^2 x 7

585 = 3^2 x 5 x 13

675 = 3^3 x 5^2

693 = 3^2 x 7 x 11
