How many permutations are there of the word collect if the 2 l's have to be together and the two c's have to be separated?

I got as far as 360 because if u keep the l's together you would get

__6! x 2!__

2! x 2!

but after that im stuck on what to do next

and the other question:

How many ways can 4 couples be seated at a circular table so that the couples are never sitting together?

i knoe 8! / 8 gives the possibilities of all of them at one table, but since some of them can sit together i dont know what to do

can someone help me finish of these questions?
