For this kind of question, I would suggest looking up a table of prime numbers. As an alternative, you can try to find factors for each of the numbers - if it has a factor, it is NOT a prime. For this range of numbers, testing for prime numbers up to 13 is appropriate. (If 17 is a factor of one of these numbers, the other factor is less than 17, so you would already have found it before you reach 17.)

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.
NO. There are more prime numbers between 1 and 100 than the prime numbers between 101 and 200.number of prime numbers between 1 and 100 = 25number of prime numbers between 101 and 200 = 20
The prime numbers between 41 and 54 are 43,47,53.
Prime numbers between 71 to 80 = 73 and 79 Therefore there are 2 prime numbers between 71 to 80.
Two prime numbers, 61 and 67, are the only prime numbers between 60 and 70.
