RC4 uses a 256bit key. Both these keys seem rather small in comparison to something like PGP's 1028bit key.128bit key is about 40 digits - NSA approved - breakable by a PC in a few hours.
If you can manage to break a 128 bit RC4 key in a few hours on your machine, then you likely have about a fifty billion way multiprocessor hanging out on your desk. Key lengths from different cryptosystems DO NOT map into each other. Factoring a 128 bit number is fast -- breaking 128 bit IDEA keys is not computationally feasable.
