Extract Unique Substring from Range of Excel

I have cell values with names that are fairly close to each other. I would like to extract a common sub-string.

Here is an example.

1100_250_Jump_12HR_100MD_S_run1 
1100_250_Jump_12HR_100MD_S_run2
1100_250_Jump_12HR_100MD_S_run3 
1100_250_Jump_12HR_100MD_S_run4 
1101_250_Jump_12HR_100MD_U_run5 
1101_250_Jump_12HR_100MD_U_run6 
1102_250_Jump_12HR_100MD_U_run7 
1102_250_Jump_12HR_100MD_U_run8 
1102_250_Jump_12HR_100MD_U_run9 
1102_250_Jump_12HR_100MD_U_run10

The output should be _250_Jump_12HR_100MD_

How can I extract a common sub-string in Excel?

I checked similar questions but could not find the answer.
