The last prime before 400 is 397.
The prime factorization of 400 is 2x2x2x2x5x5.
2 would be a counterexample to the conjecture that prime numbers are odd. 2 is a prime number but it is the only even prime number.
No.
Prime numbers have as factors the number 1 and their own number. Example: 37 is a prime number because its only factors are "1" and "37". If the prime number had further factors, it would no longer be prime.
No It is not a prime number. There are two ways you can tell its not prime. First of all, their is only one even number that is prime, and the number would be 2. Second, 74 is a composite number, therefor it cannot be prime. Hope it helps you a bit :)
no, factors of a number would be less than that of the original number. A prime number is a number that has factors of only itself and 1.
No, never. It would be divisible by the prime number.
The question is tautological. If the answer was not a prime number then thye question would not be called a prime number question!
No, it would not.
2 would be a counterexample to the conjecture that prime numbers are odd. 2 is a prime number but it is the only even prime number.
No.
A number as a product of prime numbers would be "x".
the two prime numbers will be factors of that number, which would make that number a composite number
yes
It is impossible. 2 is the only prime number that is even, all other even numbers are divisable by 2 and therefore not prime. In order to get a remainder of two when dividing by 4, the number must be divisable by 2 but not four. Therefore, any prime number that is divided by 4 would have a remainder of either 1 or 3.
Prime numbers have as factors the number 1 and their own number. Example: 37 is a prime number because its only factors are "1" and "37". If the prime number had further factors, it would no longer be prime.
29 is a prime number
