intersection

Suppose I have a list of lists of elements which are all the same (i'll use ints in this example)

[range(100)[::4], range(100)[::3], range(100)[::2], range(100)[::1]]

What would be a nice and/or efficient way to take the intersection of these lists (so you would get every element that is in each of the lists)? For the example that would be:

[0, 12, 24, 36, 48, 60, 72, 84, 96]
