Prime numbers from 1 to 50
Prime Number. A prime number (or a prime) is a natural number that has exactly two distinct natural number divisors: 1 and itself. For example, there are 25 prime numbers from 1 to 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, The prime numbers between 1 and 50 are: 2,3,5,7,11,13,17,19,23,29,31,37,41,43, There are overall 15 prime numbers between 1 and

I want to print prime numbers between 1 to But I don't understand what I am doing beween in my code. In your IF clause you are assigning the value instead of comparison. You could certainly cap the numbers you are checking against in the where condition to reduce your overheads further. How are we doing? Please help us improve Stack Overflow.

So, 50 is a 'composite number'. List of prime numbers before 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, Here you'll find the answer to questions like: Prime numbers from 1 to Get all the prime numbers from one to The prime numbers between 1 and 50 are 2, 3, 5, 7,., 41, 43, 47 Total Count of Numbers = 15 step 2 Find the sum of prime numbers between 1 and There are 15 prime numbers from 1 to They are 2,3,5,7,11,13,17,19,23,29,31,37,41,43, Answer verified by Toppr Upvote (0).
A prime number or prime is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem , there are an infinite number of prime numbers.
Subsets of the prime numbers may be generated with various formulas for primes. The first primes are listed below, followed by lists of notable types of prime numbers in alphabetical order, giving their respective first terms. The following table lists the first primes, with 20 columns of consecutive primes in each of the 50 rows. There are known formulae to evaluate the prime-counting function the number of primes below a given value faster than computing the primes.
Below are listed the first prime numbers of many named forms and types. More details are in the article for the name. Primes that are the number of partitions of a set with n members. The next term has 6, digits. OEIS : A A circular prime number is a number that remains prime on any cyclic rotation of its digits in base Some sources only list the smallest prime in each cycle, for example, listing 13, but omitting 31 OEIS really calls this sequence circular primes, but not the above sequence :.
Primes that remain prime when read upside down or mirrored in a seven-segment display. Primes that become a different prime when their decimal digits are reversed. The name "emirp" is obtained by reversing the word "prime". Of the form n! As of August [update] these are the only known Fermat primes, and conjecturally the only Fermat primes. The probability of the existence of another Fermat prime is less than one in a billion.
Fortunate numbers that are prime it has been conjectured they all are. Primes that are a cototient more often than any integer below it except 1. Odd primes p that divide the class number of the p -th cyclotomic field. They are also called full reptend primes. Primes p for base As of [update] , there are 51 known Mersenne primes. The 13th, 14th, and 51st have respectively , , and 24,, digits. As of [update] , this class of prime numbers also contains the largest known prime: M , the 51st known Mersenne prime.
As of December [update] four more are known to be in the sequence, but it is not known whether they are the next: , , , As of June , these are the only known double Mersenne primes, and number theorists think these are probably the only double Mersenne primes. For other small a , they are given below:. This form is prime for all positive integers n. Primes for which there is no shorter sub-sequence of the decimal digits that form a prime.
There are exactly 26 minimal primes:. Primes p for which the least positive primitive root is not a primitive root of p 2. Three such primes are known; it is not known whether there are more. It seems likely that all further permutable primes are repunits , i. These are also class 1- primes.
Primes for which there are more prime permutations of some or all the decimal digits than for any smaller number. Primes p that do not divide the class number of the p -th cyclotomic field. Also called primes congruent to d modulo a. The fourth Smarandache-Wellin prime is the digit concatenation of the first primes that end with As of [update] , these are the only known Stern primes, and possibly the only existing. Primes that are also a prime number when rotated upside down.
This, as with its alphabetic counterpart the ambigram , is dependent upon the typeface. Primes that are both left-truncatable and right-truncatable. There are exactly fifteen two-sided primes:. As of [update] , no Wall-Sun-Sun primes are known. Primes that having any one of their base 10 digits changed to any other value will always result in a composite number. As of [update] , these are the only known Wilson primes. As of [update] , these are the only known Wolstenholme primes.
