No, there is no last prime number. They go on forever.

The last prime number before 50 is 47.

The last prime number before 100 is 97

There is no last twin prime: they go on forever.

There is no last prime number: they go on for ever. The first prime larger than 100 is 101.

A balanced prime number is a prime number that is equal distance from the last prime before it and the next prime after it. Example: 53 is a balanced prime. The last prime number before it was 47 and the next prime after it is 59. (53 - 47) and (59 - 53) both equal 6, so 53 is a balanced prime.

Last prime of the 20th Century was 1999. Last prime of the 21st Century will be 2099.

997 is the last 3 digit prime number

There cannot be the last two prime numbers because there are an infinite number of them.

It is: 2+97 = 99

No even number is a prime number - except 2. If the last digit is 0, 2, 4, 6, or 8, the number is divisible by 2, and therefore not a prime number.

If two of the prime factors are 2 and 5, the last digit of the number will be zero.

its a multiple of 5....

Yes. Since 7 is a prime number, you have found all the prime numbers, with 7 being the final prime factor.

Yes, in fact, there is no last prime number - the set of prime numbers is infinite. The proof was already known 2000 years ago: If you assume that there is a last prime number, multiply all prime numbers up to that "last prime number". Then add one. The result is either a prime number itself, or it is composed of factors, none of which is one of the prime numbers you multiplied (because of the added 1). Thus, the original assumption (that there is a last prime number) has to be false. Example: The first 3 prime numbers are 2, 3, 5. If you multiply them, you get 30. Add one to the result, and you get 31. This number isn't divisible by 2, by 3, nor by 5. It happens to be a prime, but this isn't always so.

The last digit is a 2 which implies that the number is divisible by 2. So 46832 is not prime, it is composite.

Because it's the only even prime number. It's also the last.

no, because it has a 2 at the end. if the last digit in the number is an even number, then it is not a prime number. Also if the only factors of the number is 1 and itself then it is a prime number. example 1: 5,622 = not prime number.... example 2: 13=prime number because the only factors are 1 and 13.

last number should be a prime number
