FromDigits /@ Permutations[Range[9], {4}]

MapThread[Power, Transpose [FactorInteger[1234]]]

MapThread[Power, Transpose [FactorInteger[#]]] &[FromDigits /@ Permutations[Range[9], {4}]]

Expression 1 and 2 work, so why not 3???

General goal:
Find the factors of all permutations of the digits 1-9 with length 4(with the factors raised to their respective powers).

Shouldn't it be:
MapThread[Power, Transpose [FactorInteger[#]]]& @ (FromDigits /@ Permutations[Range[9], {4}])
?

Indeed it should :) Thanks.
Minor mistake:
MapThread[Power, Transpose [FactorInteger[#]]]& /@ (FromDigits /@ Permutations[Range[9], {4}])
