finding duplicate values in variable length columns in an array

I have a structured array with 7 different field names that are single column vectors. They are of variable lengths. For example field name 1 has 27000 values. Field name 2 has 17000 values...field name 7 has 6000 values, etc. The values are are integers that represent event IDs. I would like to find the values common to all 7 field names (columns). Any suggestions?
