There is no simple way of doing it in Excel. It would take long and complex formulas. There is a function called MOD which will give you the remainder when you divide a number into another one. If a number is a factor, then it will return zero. To check for a Prime number you would have to use it lots of times on the same number, which is not really practical. It is better to do it in a computer program. Even now, mathematicians are still finding new prime numbers, so it is a complex process, and well beyond what is practical to do in Excel.
