adding data from multiple sheets based on unique ID

Hi,

I have three sheets. Each sheet as a column with a unique ID. All three sheets will not have the same total number of IDs.

I need to match the ID in sheet 1 and 2, then take the data from sheet 2 and add it to the row in sheet 1. Then I need to do the same for sheet 3.

So sheet 1 is like this:
unique ID Data
1 x
2 d
3 ff
4 wff
5 sdfs

Sheet 2 is like this:
unique ID sheet2Data
3 aa
1 bb
4 cc

The end result I want is:
Sheet 1:

unique ID Data sheet2Data
1 x bb
2 d
3 ff aa
4 wff cc
5 sdfs

I have no idea how to do this.

thanks for any input.
