73 is a prime number because it can only be divided evenly by 1 and itself.

You know that except number 2 all other even numbers are not prime numbers. You also know except number 5, all other numbers divisible by 5 are not primes.You can also find it by dividing or by primefactorisation.

I hope my answer helped.! :)
