There are infinitely many prime numbers.Prove this by contradiction.Suppose we have Q = p1p2p3.....pn + 1 where p's are primes. Either Q is prime or composite. Divide both sides by any of the prime integer. However, p doesn't divide 1. So Q is a prime number. Thus, there are infinitely many prime numbers.
To determine the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888, we can use the Prime Number Theorem. This theorem states that the density of prime numbers around a large number n is approximately 1/ln(n). Therefore, the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888 can be estimated by dividing ln(8888888888888888888888888888888888888888888888) by ln(2), which gives approximately 1.33 x 10^27 prime numbers.
5To get the number of prime numbers in a number, divide by the lowest prime number that divides exactly, then keep going until you end up with a prime number. 300 - 2150 - 275 - 325 -55
The answer depends on how many prime numbers are whose!
13 prime numbers
