A prime number can ONLY be divided by itself AND one. Primes have two distinct factors, themselves and one.

So when someone asks, ‘Is 1 a prime number?’ You can confidently say no and refer them to the poster below and mention how ‘itself’ IS one 😉

Hint – Have a look at the last digit of each number and apply the above rules.
