5, all other numbers ending in 5 are divisible by 5.

No. If they end in 4, they are even numbers and divisible by 2, and therefore are not prime.

Two and five!

because all other numbers that end with 5 are divided by 5, in which case they are not prime!

No. Other than 5, no prime numbers end in 5.

Other than 2, no prime numbers are even. So prime numbers can't end in even numbers. After 5, no prime number can end in 5. After 5, all prime numbers end in 1, 3, 7 or 9.

The only prime number that ends in 5 is 5. All other numbers that end in 5 are multiples of 5 and would have more than two factors.

All numbers larger than 5 which end in 5 are divisible by 5 and so are not prime. All numbers larger than 2 which end in 2 are divisible by 2 and so are not prime.

5 and 2 are the only prime numbers that end in a 5 or 2. A prime number is by definition only divisible by 1 and itself, and all other whole numbers ending in 5 or 2 are divisible by 5 or 2, respectively. Numbers that are not whole numbers cannot be prime.

You end it when all the numbers are prime.

5, all other numbers ending in 5 are divisible by 5.

32 is not a prime because 2 is a factor of all even numbers. 95 is not a prime because all numbers greater than 5 that end in a 5 or 0 are composite numbers.

Lots of prime numbers have zeros in them. 101, 103, 107 and 109 are all prime numbers. Prime numbers can't end in zero. Numbers that end in zero are multiples of ten and have too many factors to be prime numbers.

No.

No. If they end in 4, they are even numbers and divisible by 2, and therefore are not prime.
