105 is not a Prime number. You can readily see that 3 and 5 go into it, and 7 goes into it too. The number ends in 5, and 5 goes into any number ending in 0 or 5. The sum of the digits is 6, and when the sum of the digits is divisible by 3, then so is the original number.
105 is not a prime number among them. It is because it is divisible by 5.
Assuming you meant 101, 103, 105 & 107... The number 105 is not prime - as it will divide by 5 or 3.
97 101 103
The prime numbers between 80 and 105 are: 83, 89, 97, 101, 103
Eleven numbers less than 105 are relatively prime to 105. They are 82, 83, 86, 88, 89, 92, 94, 97, 101, 103, and 104.

The prime numbers between 80 and 105 are: 83, 89, 97, 101, 103
Eleven numbers less than 105 are relatively prime to 105. They are 82, 83, 86, 88, 89, 92, 94, 97, 101, 103, and 104.
61, 67, 71, 73, 79, 83, 89, 97, 101 and 103.
The numbers 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101 and 103 are prime.
To find the mean of all prime numbers between 90 and 115, we first list out the prime numbers in that range: 97, 101, 103, 107, 109, 113. Then, we calculate the sum of these numbers: 97 + 101 + 103 + 107 + 109 + 113 = 630. Finally, we divide the sum by the total count of prime numbers (6) to find the mean: 630 / 6 = 105. Therefore, the mean of all prime numbers between 90 and 115 is 105.
