What are 2 prime numbers whose sum is an odd number?
It could any odd prime number and 2 since 2 is the only even prime number and add whole numbers to an odd sum requires both odd and even.In other words, 2 and any other prime will work.
What is the whole number greater than 1 with only two factors 1 and itself?
Two.A number with only two factors, one and itself, is called a prime number. The only even whole prime number is two. Your question implies that there is only one whole number greater than one which is prime, however, since odd numbers are whole numbers, and odd numbers (but not even) are prime, there are infinite prime numbers (since no one has checked each number to infinity to see if it's prime, and, obviously, never will, most assume that the list of prime whole numbers is not finite). Examples are 3, 5, and 13. 9 is an example of an odd number which is not prime.
Does every number have a prime factorization?
Yes even numbers that's not a whole number.Ex: 1.39
What is the greatest 8 digit even number using prime digits?
To be an even number then the final digit = 2. The largest single prime digit is 7 (as both 8 and 9 are composite). The greatest even number fulfilling the conditions is 77777772.
What number is both odd and even?
No number can be both odd and even. In mathematics, odd numbers are integers that are not divisible by 2, while even numbers are integers that are divisible by 2. Since these definitions are mutually exclusive, a number cannot be both odd and even simultaneously.
