Eight pairs. Two prime numbers M and N are twin primes if |M-N| = 2. So here are the list of prime numbers less than 100:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.
There are 8 pairs of twin primes here:
- 3,5
- 5,7
- 11,13
- 17,19
- 29,31
- 41,43
- 59,61
- 71,73

How many prime numbers between 1 and 8888888888888888888888888888888888888888888888?
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.
How many twin prime pairs are between 65 and 105?

What are co-prime numbers between 1 to 200?
Co-prime numbers, also known as relatively prime numbers, are pairs of numbers that have no common factors other than 1. For example, the pairs (8, 15) and (9, 28) are co-prime because their greatest common divisor (GCD) is 1. In the range from 1 to 200, many co-prime pairs exist, such as (14, 25), (20, 33), and (99, 100). Essentially, any two prime numbers are co-prime, as well as any two numbers that do not share any prime factors.
