What is a positive integer with only one factor?
The positive integer with only one factor is 1.
What is the difference between factors and prime factors?
A factor of a integer is an integer that divides the second integer into a third integer exactly; i.e. A is a factor of B if B/A is exactly C, where all of A, B and C are integers. A prime factor is a factor as above, but is also a prime number. This means that the only factors of that factor are one and the number itself; i.e. A is a prime factor of B if B/A is exactly C andthe only factors of A are 1 and A.
Why is 1 and 0 nor prime or composite?
A prime number has two positive integer factors, itself and 1. The number 0 has no positive integer factors, and is therefore not prime. The number 1 has just a single positive integer factor, and once again, is not prime.
What is the definion factor and prime number?
A factor is a number or algebraic expression by which another is exactly divisible. A prime number is a positive integer with two factors: one and the number itself.
How many prime numbers are divisible by 2?
Since a prime number has only two positive integer factors, itself and 1, the only prime number with 2 as a factor is the number 2 itself.
What are the numbers that are not prime or composite?
A prime number is a number with two positive integer factors, while a composite number has more than two positive integer factors. Since the number 0 has no positive integer factors, and the number 1 has just one positive integer factor (itself), neither of these are prime.
What is the only number between 1 and 50 that is neither prime nor composite?
The integer 1 is not considered to be a a prime or a composite number because it has only one factor which is itself.
Can 3 over 10 be simplified?
No; 3 is a prime number with no factors other than itself and 1, and 3 is not an integer factor of 10.
What is the greatest common factor of three odd prime numbers?
A prime number is an integer, a, that can only be expressed as a * 1 = a; a > 0. It has no other factors save for 1 and itself. Thus, the only common factor of 2 or more prime numbers is 1.
Which integer is a prime factor of 20?
The prime factors of 20 are: 2 and 5.
How come one is not a prime number?
The definition of a prime is an integer that has two positive factors, one and itself. These are two distinct factors. One only has one positive factor. Thus it's not a prime.
Why can't we use 0 or 1 as a prime or composite number?
A prime number has just two positive integer factors, itself and 1. Therefore, 0 and 1, which have none, and one, positive integer factor respectively, are not prime. A composite number has more than two positive integer factors - that is, including itself and 1. Therefore, since 0 and 1 do not have more than two positive integer factors, they are not composite, either.
