You don't. All prime numbers are also whole numbers.

All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.

yes they are

Numbers divisible by 1 & number itself are called prime numbers. These numbers also have the property to be odd numbers.

Square numbers can't be prime. They have too many factors.

They are prime numbers when you reverse the first one, the second one is prime also.

no,its not always......for example see 23.........but it's reverse(32) isn't prime.

Some numbers that you can get when you reverse the digits and they are still prime numbers are: 403 ÷ 13 = 31 2,701 ÷ 37 = 73 1,207 ÷ 17 = 71

"emirp" is "prime" spelled backwards. An emirp number is a prime number whose reverse is also a prime. However, palindromic primes are excluded. So 13 / 31 are emirp numbers.

You don't. All prime numbers are also whole numbers.

There are no other prime numbers that are even but 2.

This can be an extension to the proof that there are infinitely many prime numbers. If there are infinitely many prime numbers, then there are also infinitely many PRODUCTS of prime numbers. Those numbers that are the product of 2 or more prime numbers are not prime numbers.

The only even prime number is 2.

It's not.

All prime numbers are odd numbers. If one were even, it would be divisible by two and would, therefore, not be prime.

The numbers are relatively prime, or co-prime.

Yes. In general, if you have two different prime numbers, they will also be relatively prime.
