Here is a very simple algorithm: Call your number "n". You might test divisibility by every number, starting at 2. If the first number by which a number is divisible is equal to "n", then it is a Prime number. - Faster algorithms are possible; for example, you really only need to test divisibility by all numbers, up to the square root of your number "n".

What is an algorithm for multiplying rational numbers?
The algorithm is A/B * C/D = AB/CD.
Write a C program to find the sum of all prime numbers?
Since there is an infinite set of prime numbers the answer would be infinity.
Which of these numbers is not a prime number A 21 B 31 C 41?
21 is not a prime.
How do you show that 2 and 3 and 5 and 7 are mersenne primes?
The algorithm for a Mersenne prime is 2n - 1, where n is a prime number and the solution is also a prime number.Applying the Mersenne algorithm to the prime numbers 2, 3, 5, and 7:22 - 1 = 3, 23 - 1 = 7, 25 - 1 = 31, and 27 - 1 = 127.3, 7, 32, and 127 all being prime numbers, this demonstrates the 2, 3, 5, and 7 are all Mersenne primes.
Is 21 and 35 relatively prime?
You need to check whether they have a common factor. You can simply factor each of the numbers; for numbers that are much larger, using Euclid's algorithm is much faster.If the common factor of two numbers is greater than 1, then they are NOT relatively prime.
