How can you tell that 32 and 95 are not prime numbers without finding their factors?

Sagot :

Last digit of 32 is 2 then even number then not prime ( only 2 is prime and even)
Lst digit of 95 is 5 then is dividing by 5 then no prime

-- 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.
