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.
Write an algorithm to check whether a number is a prime number or not?
You can write out this algorithm. This will then be programmed into the device to make determining prime numbers easier.
What is an algorithm for multiplying rational numbers?
The algorithm is A/B * C/D = AB/CD.
Is there an algorithm that yields only prime numbers?
What exactly do you mean "yields only prime numbers"? If you mean a formula that when given the numbers n=1, 2, 3, ... and so on generates the nth prime number (or a different prime number for each n) then no. If you mean an algorithm whereby a number can be tested to be a prime number then yes. (Using this prime_test algorithm, a simple algorithm can be written that would supply numbers one at a time to it and use its result to decide whether to yield the tested number or not, only yielding those numbers which pass the test.)
Did eratosthenes make a mistake in prime numbers?
The algorithm for identifying prime numbers which is known as the Sieve of Eratosthenes has been accepted as accurate for thousands of years.
All even numbers from 2-100 using algorithm?
102
What is the GCF of 180 336 and 504?
You can use Euclid's algorithm to calculate the gcf of two of the numbers - then use Euclid's algorithm again with the result and the third number.Or you can factor all the numbers into prime factors, and check which prime factors occur in all three numbers.
Design a algorithm to generate all prime numbers within the limits l1 and l2?

How many prime numbers are located on sieve of erastosthenes?
The sieve of Eratosthenes is a simple, ancient algorithm for finding all prime numbers up to any given limit.
Is there any specific formula for finding out that the given numbers are relatively prime?
Euclid's algorithm is probably the most commonly used 'formula' for that purpose. If the greatest common factor is 1, the numbers are relatively prime. See the related question for an example of Euclid's algorithm.
How do you find 2 prime numbers that if multiplied would generate a 400-digit number?
You seek for prime numbers that are approximately 200 digits big, then multiply them. I don't know details about the algorithms, but I understand that for cryptography, instead of using an algorithm that will be guaranteed to give a prime number, an algorithm is used, instead, that has a very, very high probability of giving a prime number. Probably this is done because it is faster.
How do you describe an algorithm with rational numbers?
Describe an algorithm for dividing rational numbers.
