Inserting the same formula/multiplier across multiple cells

I have an excel spreadsheet with with 17 numeric columns that represent baseball stats. I would like to multiple all of the data in each of those columns and rows (20) by 1.434. Rather than go in and take each individual # in each column and manually key in =#*1.434 I would like to know how to globally apply that formula across the spread sheet. Manually keying would take me 45-60 minutes per sheet.

PURPOSE OF FORMULA: I am attempting to project baseball stats from the 1994 strike season for each team and each player over the 162 games that should have been played. Since each team played a uneven amount of games I am applying different amounts in the formula to bring them close to 162. I can send the spreadsheet to anyone who is interested if they'd like to tinker with it. I think I uploaded it here as well94Chisox.xls

Thanks, it worked like a charm !!!
