Find all prime numbers [tex](p,q,r)[/tex], that numbers [tex]pq+pr+rq[/tex] and [tex]p^3+q^3+r^3-2pqr[/tex] are divided by [tex]p+q+r[/tex]
Prime numbers are positive integers that are only divisible by 1 and themselves. Examples of prime numbers include 2, 3, 5, 7, 11, and so on.
To determine if a number is prime, you can divide it by all the numbers between 2 and the square root of the number. If the number is only divisible by 1 and itself, then it is a prime number.
Prime numbers are numbers that are only divisible by 1 and themselves, while composite numbers have more than two factors. For example, 6 is a composite number because it is divisible by 1, 2, 3, and 6.
Yes, this is known as the fundamental theorem of arithmetic. It states that every positive integer can be expressed as a unique product of prime numbers.
Prime numbers play a crucial role in cryptography as they are used in generating large, secure encryption keys. They are also used in algorithms for data encryption and decryption.
