How can you tell that 32 and 95 are not prime numbers without finding their factors?
-- The last digit of 32 is an even number. The only even prime number is 2. All of the other prime numbers are multiples of 2, so 32 can't be a prime.
-- The last digit of 95 is 5. That tells us that it's a multiple of 5. The only multiple of 5 that's a prime number is 5 itself. 95 is not 5 itself, so it's not a prime.
