Fact Table Question

I have a fact table which is composed of 5 foreign keys and one numeric value. Is there any benefit to creating a primary key bitmap index on the 5 foreign key columns together vs just creating 5 individual bitmap indexes on the foreign keys? I know the primary key will perform the unique checking, but it seems like the individual indexes will be better used for querying. Am I missing something? Is there a reason to go one way or the other?

Thanks,
