Multiply every combination of numbers possible. If nothing equals the number you want to know is prime, it's prime. One quick check you can make: if the number is 2 digits or more and it ends in 0, 2, 4, 5, 6 or 8, then it most definitely is NOT prime. For all other numbers, you have to do some calculating to be sure.
