Combine logical arrays into one array

I have 4 '24871x1 logical' called L1, L2, L3, L4. I want to combine these into one 24871x1 logical array. In any given row only one of the four arrays will have a 1. I want the output array to have a 1 if there's a 1 in any row of L1-4 and 0 if all rows are 0 in L1-4. Can anyone advise how I do this?

L = L1 | L2 | L3 | L4;
