Can a nonprime multiplied by a nonprime ever result in a prime?
NO!!! By the fact that you are multiplying two numbers together, the answerv is ALWAYS composite.
What does the DIVSUM function does?
The DIVSUM function calculates the sum of the divisors of a given integer, excluding the integer itself. For example, for the input 12, the function would return the sum of its divisors 1, 2, 3, 4, and 6, which equals 16. This function is often used in number theory and can help identify perfect numbers, abundant numbers, and deficient numbers based on the sum of their divisors.
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.
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.
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.
What kind of numbers are 31937 and 131?
The numbers 31937 and 131 are both integers. Specifically, 31937 is a five-digit prime number, meaning it is greater than 1 and has no positive divisors other than 1 and itself. On the other hand, 131 is also a prime number, being a three-digit integer that similarly has no divisors other than 1 and 131. Both numbers belong to the set of natural numbers.
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.
Which of the numbers 31 41 51 and 61 is a composite number?
A composite number is a positive integer greater than 1 that has more than two distinct positive divisors. In this case, the number 51 is a composite number because it has divisors other than 1 and itself, such as 3 and 17. Numbers 31, 41, and 61 are all prime numbers, as they only have two distinct positive divisors, 1 and the number itself.
Are these numbers composite 30 31 32 33 34 35 36 37 38 and 39?
31,37 are not composite
How do you use divisors?
Divisors are used to divide numbers.
Why are the numbers 6 and 28 important?
The numbers 6 and 28 are significant in number theory as they are both classified as perfect numbers. A perfect number is a positive integer that is equal to the sum of its proper divisors, excluding itself. For example, the divisors of 6 are 1, 2, and 3, which sum to 6, while the divisors of 28 are 1, 2, 4, and 7, which also sum to 28. These numbers have fascinated mathematicians for centuries and are connected to the study of number patterns and the properties of divisors.
