#&@@(1##&@@FactorInteger@#)& avoids the need to Transpose altogether. (1##&@@ is just Times@@ in disguise, which works great on the ordered pairs yielded by FactorInteger; and '#&@@ is First@ in disguise.)

You can also use Thread instead of Transpose. In Mathematica there's also a 3-byte operator for Transpose, but I don't know whether Mathics supports it.

Times@@#&@@Transpose@FactorInteger@#& saves 3 bytes (#&@@ is standard trick for [[1]] and in cases like this it can often save some extra bytes on parentheses).
