Which of the following is the only even prime number?
Therefore, 2 is the only prime number that is even and the rest of the prime numbers are odd numbers, hence called odd prime numbers. The prime numbers that have only one composite number between them are called twin prime numbers or twin primes.
How many prime numbers are there below 10 23?
The first 1000 prime numbers. This has been used to compute that there are 1,925,320,391,606,803,968,923 primes (roughly 2 × 10 21) below 10 23. A different computation found that there are 18,435,599,767,349,200,867,866 primes (roughly 2 × 10 22) below 10 24, if the Riemann hypothesis is true.
What are the factors of the first ten prime numbers?
If p is a prime, then it’s only factors are necessarily 1 and p itself. Any number which does not follow this is termed as composite numbers, which means that they can be factored into other positive integers. The first ten primes are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29. Note: It should be noted that 1 is a non-prime number.
