For various reasons very large prime numbers play an important role in various kinds of password and identification security. It is thought (although this is hardly a practical real-life situation) that the 17 Year Locust evolved to its 17 year span because the primality of 17 gave it advantages over perennial predators.
Any situation numbers are used.
Prime numbers are used to find the LCM of numbers Prime numbers are used to find the HCF of numbers Prime numbers are used to simplify fractions Prime numbers are used to find the LCD of fractions
Data encryption, used for personal identification numbers (PINs) and for secure communications over the internet are based on very large prime numbers.

Prime numbers are used to encrypt credit cards and identify them.

Yes they are most likely used in your everyday life- even if you don't realize it. Computers use prime numbers in the encryption techniques. If you log in to a website in secure mode, most likely prime numbers are being used, but you don't even know about it.
Real numbers are used in real life in like the discount prices of a sale or when a teacher grades your paper.... there are lots more... :) ADDED: Put simply, the Real Numbers are those in which we count or measure real things: objects, people, money, distances, weights, etc..

we have 7 days in a week. 7 is a prime number. there are 31 days in some months.31 is a prime number
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
