Here's one way:

So, is this some contest akin to Neopets/Lenny Conundrum?

Here six solutions starting with each of the remaining digits 1 2 3 5 7 9.


1 * (((5 + (7 * 3)) * 9) * 2) = 468
2 / ((1 / (5 + (7 * 3))) / 9) = 468
3 * (((9 * 5) + 7) * (1 + 2)) = 468
(((5 + 2) / (1 / 7)) + 3) * 9 = 468
(7 + (2 * 3)) * (9 * (5 - 1)) = 468
9 * ((5 * (3 * (1 + 2))) + 7) = 468
