What are prime numbers used for in the real world?
cryptography
How do you use prime numbers in real life?
Data encryption, used for personal identification numbers (PINs) and for secure communications over the internet are based on very large prime numbers.
How is prime and composite numbers used in the real world?
we have 7 days in a week. 7 is a prime number. there are 31 days in some months.31 is a prime number
Is 333.6666666666667 a prime number?
The concepts of "prime numbers" and "composite numbers" make sense for integers (whole numbers), not for arbitrary real numbers.
What is a real world example of a prime number?
2 is a real world prime number.
What makes prime numbers and composite numbers related?
Prime numbers are related with composite numbers as they are both natural numbers and real numbers and also every composite number is a product of prime numbers due to which they are related with each other.For example 24=[2] [2] [3] [2].Here 24 is a composite number,real number and natural number and 2,2,3,2 are prime numbers and also they are real and natural numbers
Why do people look for large prime numbers?
Some think it is an interesting challenge. Prime numbers of up to a few hundred digits have real practical applications, in cryptography. However, the largest prime numbers found are much, much greater than that.Some think it is an interesting challenge.

What are non-zero real numbers?
Non-Zero Real Numbers are infact complex conjugate numbers. They are negative prime numbers.
What real life situations are prime numbers used?
Any situation numbers are used.
What real-life situations are prime numbers used?
Large prime numbers are used in encryption. The larger the primes, the better the encryption. Typically each of two people will provide a prime; you need to know both prime numbers to decrypt. A program is used to calculate the values to be sent. The message is sent along with the product of the primes (sender's prime * receiver's prime). Since the number will be large it is difficult to crack (again, larger the better). To decrypt you have to know both prime numbers. Knowing one and the product makes it easy (just divide). If you only have the product, decrypting can be very time-consuming as you are forced to find the factors of the number
What are the subsets of a real numbers?
The set of real numbers is infinitely large, therefore it has an infinite amount of subsets. For example, {1}, {.2, 4, 800}, and {-32323, 3.14159, 32/3, 6,000,000} are all subsets of the real numbers. There are a few, important, and well studied namedsubsets of the real numbers. These include, but aren't limited to, the set of all prime numbers, square numbers, positive numbers, negative numbers, natural numbers, even numbers, odd numbers, integers, rational numbers, and irrational numbers. For more information on these, and other, specific subsets of the real numbers, follow the link below.
What si a real number?
All the numbers in the world are real. Therefor they are all real numbers.
