There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.

The premise of your questions is false: NOT every number is a prime number.

None. 251 is a prime number.

30 has three prime numbers and is a factor of 60.

A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.

There are no prime numbers with three factors. By definition, a prime number has exactly two factors - 1 and itself.

The only prime number divisible by three is three itself.

the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.

The question, "the" three odd prime numbers, is wrong. There are much more than three odd prime numbers - in fact, infinitely many. There are infinitely many prime numbers, and all except the number 2 are odd.

The sum of three odd numbers will be odd, whether they are prime or not. The sum of three prime numbers can be even as long as one of them is 2.

3 is a prime number because it is only divisible by 1 and itself, as are all prime numbers.

No.

Three.Three.Three.Three.

Prime numbers have two factors. Prime squares have three factors. Square numbers have an odd number of factors but that number varies.

The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.

As the number 1 is considered a special case and not a prime, there cannot be three consecutive numbers that are prime. Any three consecutive numbers must include at least one even number. With the exception of the number 2, no even numbers are prime.

No
