WitrynaYes, 2 is a prime number. The number 2 is divisible only by 1 and the number itself. For a number to be classified as a prime number, it should have exactly two factors. … WitrynaThe correct option is D 2 Factors of 35 = 1, 3, 9, 27 Factors of 2 = 1, 2 Factors of 45 = 1, 3, 5, 9, 15, 45 Factors of 18 = 1, 2, 3, 6, 9, 18 We know that a prime number has only two factors, 1 and the number itself, which is true for 2. Therefore, 2 is a prime number.

WitrynaGoldbach's conjecture is one of the oldest and best-known unsolved problems in number theory and all of mathematics.It states that every even natural number greater than 2 is the sum of two prime numbers.. The conjecture has been shown to hold for all integers less than 4 × 10 18, but remains unproven despite considerable effort. components of 8085WitrynaAll the lines in the input text file can be read in the same way. In Listing 8 , all the prime numbers betwoen 1 and 20 are listed before the hyphen (−) i.e 2, 3, 7, 11, 13,17,19.
