Matching Data between Files , Deleting Matching Rows

This forum has been absolutely amazing in helping me prep some data I have for a major DB import! Hopefully, you wonderful gurus can help me one last time.

I need a macro that will let me compare values from workbook to values in another, and then delete the rows that match.

Attached you will find two spreadsheets (Legacy Data Sample is only a small sample of a 15k record spreadsheet).

I need to check column A of worksheet 1 in SSMC DELETE against column K in worksheet 1 of Legacy Data Sample. For matching values, I need to delete the entire row in the Legacy Data Worksheet.

Then, I need to check column A of worksheet 2 in SSMC DELETE against column H in worksheet 1 of Legacy Data Sample. For matching values, again, I need to delete the entire row in the Legacy Data Worksheet.

If anyone can help, it will be much appreciated! Thanks in advance!
