The smallest ones are
735, 3792, 1341275, 13115375, 22940075, 29373375, 71624133, 311997175,
319953792, 1019127375, 1147983375, 1734009275, 7350032375.

One can also easily find some larger examples, like:

595365737037039341073 = 3^3*5953657*3703703934107

12320940000129861064893197390441900971198439075 =
5^2*123209*4000012986106489319739044190097119843907

23376432078559738134206219312602291325695581014733 =
