How to Reduce Memory requirement of large Excel workbooks ?

I'm working with large Excel spreadsheets and running into problem with the size of it. Currently it is around 45 MB and getting unstable. Is there anything I can do to reduce the memory requirements in Excel ?

I'm having around 3000 rows and 300 columns of data split on a few input sheets. Then, there are lots of analysing sheets with calculations like divisions, multiplications and lookupfunctions and if-statements and plots.

Should I avoid formatting, does the data organising impact the memory (formulas link between sheets etc.), is multiplication less demaning than division, what about Array formulas ...or.....
