Why is the number 3 a prime number?
A whole number (integer) greater than one is called a "prime number" if it has no positive divisors other than itself and one. Three is one of those numbers.
Why is the number 19 a prime number?
A whole number (integer) greater than one is called a "prime number" if it has no positive divisors other than itself and one. 19 is one of those numbers.
What number is not a prime or composite?
By definition, every integer greater than one is either a prime or a composite number. Indeed, a composite number is defined to be a positive integer which has a positive divisor other than one or itself. And a prime number is defined to be a integer greater than one which has the contrary property (exactly two divisors - one and itself). So any number greater than one is either composite or prime. Among the natural numbers, it remains the number 1, which is neither composite nor prime. 0 is composite, since has all positive integer as divisors.
Is 1 and 2 prime?
No, neither 1 nor 2 are prime numbers. A prime number is a positive integer greater than 1 that has no positive divisors other than 1 and itself. 1 only has one positive divisor (1) and 2 has two positive divisors (1 and 2), so they are not prime.
What numbers can go into 50 evenly?
50 can be divided by any number except zero; the integer divisors with integer quotients are 1, 2, 5, 10, 25, and 50.
How do you use divisors?
Divisors are used to divide numbers.
What numbers have a factor of 8 or more?
Any integer greater than 7.
What is the definition for a positive integer?
all real numbers greater than 0.
What re prime numbers?
A prime number is a positive whole number (a positive integer) that has exactly two unique positive divisors, 1 and the number itself.
How many natural numbers less than 1000 have exactly three distinct positive integer divisors?
Prime squares have three factors. There are 11 of them in that range.
Explain why multiplication of nonprime numbers never result in a prime?
The products of non-prime numbers have more than two factors.
Is a to the 3rd power greater than or equal to a for all integer values of A and why?
No. A negative integer raised to the third power will yield a negative number that is less than the integer. Only whole numbers (positive integers greater than or equal to 1) have the property where that integer raised to the third power is greater than or equal to the integer.
