Auto populate multiple cells with a value entered in one Cell

Hi,

I'm looking for a macro that auto-populates multiple cells in different columns spread across 3 worksheets in the same workbook.

I'm attaching a sample file for better understanding of the situation.

If i enter a value below the column header 'Input' in Sheet 1 the macro should automatically populate the value in all the columns with the header 'Output' in all 3 sheets. Column Headers positions will not change but their name will contain a word output.

Please let me know if any further details are required.

Best Regards
