One. 997 and 2
The answer must have an even number and an odd number, because if you add two odd numbers, the sum would be even. Therefore, the first answer is the only prime even number: 2. 2 + 997 is 999, so the other answer would be 997. 997+2 (!?!) 997+2 (!?!) 2 and 997
The prime numbers (factors) of 1000 are: 2 and 5
Two of the factors of 80 are prime numbers: 2 and 5.
There are many, many more odd prime numbers than even prime numbers; there is only 1 even prime number, namely 2, whereas the odd prime numbers are 3, 5, 7, 11, ...
One. 997 and 2
A prime number is when: The only numbers that can go inside that number is 1 and itself. So, yes. 99.9 is a prime number. By checking, you can do 99.9 divided by 2, and if its a decimal number, then its a prime.
The sum of the prime numbers between 1 and 1,000 (2-999) is 76,127.
The answer must have an even number and an odd number, because if you add two odd numbers, the sum would be even. Therefore, the first answer is the only prime even number: 2. 2 + 997 is 999, so the other answer would be 997. 997+2 (!?!) 997+2 (!?!) 2 and 997
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 prime numbers (factors) of 1000 are: 2 and 5
999 999. 1 million and 2 million aren't counted. It is only the number inbetween. so from 1000001, 1000002,.........1999998, 1999999 which is 999 999 numbers
Work back from 999:999 is odd ... no.998 is even and divisible by 2, so it is composite. (All even numbers are composite!)Further Information:-All even numbers are composite except for 2 which is a prime number.
Two. The prime numbers (factors) of 36 are: 2 and 3

The prime factors are: 2, 5
