Is every number a factor of 1 true or false?
As stated, that is false. Every number is not a factor of 1. 1 is a factor of every nonzero whole number.
Is the statement the greatest common factor of a prime number and composite number is a prime number True?
No, that's not true.
Is every number either prime or composite?
No. It IS true that every whole number is either prime or composite. But there are numbers that are not whole numbers, such as 2.5, which are neither prime nor composite.
What is the greatest three digit integer that has a factor of 32?
The number 32 has only one prime factor: 2The true prime factor for any number is 1.
Which of these statement are true 1 is a factor 0f 5?
1 is a factor of 5 which is a prime number
Is it true that a prime number is a whole number greater than 1 that has only itself and 1 as a factor?
It is true.
What is the prime factorization of all even numbers?
Because the Fundamental Theorem of Arithmetic specifies that every integer greater than 1 has its own unique prime factorization, it is impossible to specify what each of these prime factorizations is, however, it is true that the prime factorization of every even number includes the number 2 as the lowest prime factor.
Is it true that every number has a 0.5 factor?
No because factors are whole numbers but every whole number except zero has 1 as a factor.
Is it true that if two numbers have no common prime factors the greatest common factor is 1?
Yes it is, because every number at least has two factors: itself, and 1.
What is true about every prime number?
They all have only two factors.
Can the number 1 be a factor of a number?
Yes 1 is a factor of every number except 0. This is literally true but incomplete. The number 1 is a factor of any number and can be that factor an infinite number of times. Most people don't like infinity. It causes many problems. That's (partially) why 1 is not considered a prime number although it has no factors other than itself and 1 (yes, redundant to infinity). So when someone asks for prime factors of a number, be sure to not include 1. Unless you are an infinite entity and infinite time to write out the prime factors.
Why is every odd number greater than 1 not prime?
That's not true.
