I have a workbook that has two worksheets.

The first worksheet is simply a list of the first 78,498 prime numbers in a single column, A1-A78498.

The second worksheet has a grid of numbers from 1 to n.

The goal is to highlight the cells with prime numbers in the grid by referencing the prime number values in the other worksheet. Is this possible, and if so, how?

edit

I have named the column with my prime numbers "PRIMES1T".

I would like the formula to work for the entire worksheet, regardless of size, but my excel-fu is extremely weak. If at all possible, I would like to be able to enter the formula in the dialog box for conditional formatting (as below): I have tried =NOT(ISNA(MATCH(A:Z,PRIMES1T,0) (only A-Z, but have to start somewhere) with no luck.
