How do you tell if a number is a prime?
To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can’t be a prime number. If you don’t get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number (see table below).
What is the trick to finding a prime number?
Take a number, say, 26577. The unit digit of this number is not 0, 2, 4, 6 or 8. Now, take the sum of digits which will be: 2 + 6 + 5 + 7 + 7 = 27. Since 27 is divisible by 3, 26577 is not a prime number.
