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?
There is no number that is both even (divisible by 2) and odd (not divisible by 2). Even numbers are of the form 2m for all integer m; Odd numbers are of the form 2n + 1 for all integer n; Assume there is an even number is also an odd number, then for some integer m and n: 2m = 2n + 1 � 2m - 2n = 1 � 2(m - n) = 1 � m - n = 1/2 But as m and n are both integers, their difference cannot be a fraction. Thus there are no integer m and n that satisfy 2m = 2n + 1, which means that the original assumption that there is an even number that is also an odd number is false. Thus there is no number that is both even and odd. This question is actually a riddle. The answer is 6 or 9, since flipping either number will give you the other.
Is even number times even number always even?
Yes, it is. Any whole number times an even number will be even. This is because whole numbers can be represented as the product of their prime factors. Every even number contains 2 as a prime factor (thereby excluding all even numbers above 2 from being prime.) Additionally, the product of any two numbers is equal to the product of their prime factors. This means that the result of multiplying an even number by a whole number will always have a prime factor of 2, making it an even number.
Why can't a whole number ending with 8 be a prime?
The only even prime number is 2.
Which is the smallest even whole number?
It is 2 which is also the only even prime number
Can a number ending in 0 be a prime number?
No. All whole numbers ending in zero are even. The only even prime number is two.
Who discovered when any even number added with a prime number makes a whole number?
It doesn't have to be a prime number and an even number. The sum of any two whole numbers is a whole number. Also, the sum of two even numbers is an even number, the sum of two odd numbers is an even number, and the sum of an odd number and an even number is an odd number.
What number is both a prime number and an even number?
2
Which number is both prime and even?
2
What numbers are both prime and even?
There is only one even, prime number. It is two (2).
Difference between Even number and Prime Number?
A prime number is a number that can only be divided by itself and 1. An even number is pretty much the opposite, it can be divided by 2 or more. There is one number in fact that is both a prime number and even number, which is two as it can be divided by itself and 1.
What is the 1st prime number?
The first prime number is 2 even though it is even, because a prime number is a number that has two multiples, one and itself(it can only be divided by one whole number : one) Your Welcome
What is the only number which is both even and prime?
