Find 13 equal columns out of the existing 14

HELP.

I have in the link below the CSV file with 4,782,969 records.

  https://azhivw.dm.files.1drv.com/y4mkm8-0scnW2IvW98j-RDc1vXpYg2k6YkQdVlQD2URN6dbB18LZLXtqNDrkVH9Ns55RQFz3A7dXBm4TV8qZMd0eS1-8d30nQnSt7nnp1zi1gqgznwK-yGl_sqmXbuBMmpNoIPja0zbUoS30ieoTMVWTh-iM4a7UxdQUqjhHhMzpZXpnC9KmTH1n1sfQND5dD09/14sNumeros.csv.zip?download&psid=1


Id, COLL1, COLL2, COLL3, COLL4, COLL5, COLL6, COLL7, COLL8, COLL9, COLL10, COLL11, COLL12, COLL13, COLL14

For each of the lines would need to compare with the 4782969 and find the 28 lines where there are 13 of the 14 equal columns and generate a new CSV with ID, ID2,

Since the ID is the ID and the ID2, the 28 ID's that contain 13 columns are the same.

With help, make a query but is very slow.

Import CSV to Table [Tbl14ids]  

And

CREATE TABLE [dbo].[Famaly13](
[MAIN] [int] NULL,
[CHILD] [int] NULL
) ON [PRIMARY]
GO
