Prime roots of large numbers

[murdlih]

I is not a mathematician, but I had heard a tale of someone in my family using Excel to find the prime roots of a 10 digit number. I am also not a computer programmer, but after 10 minutes of poking around in excel, I have discovered that one of the roots of my 10 digit number is two digits, and all the rest are greater than 500,000.

Also, I just checked, and there are only 2 roots to my 10 digit number. The second one is 8 digits long.
