To find all the prime numbers between 15 and 25, we can check each number in this range individually and determine if it is prime or not.
A prime number is a positive integer greater than 1 that has no factors other than 1 and itself. Therefore, we need to check if each number in the range has any factors other than 1 and itself.
Let's go through each number in the given range and check if it is prime:
Starting with 15:
- 15 is divisible by 3 and 5, so it is not a prime number.
Moving on to 16:
- 16 is divisible by 2, 4, 8, and 16, so it is not a prime number.
Next is 17:
- 17 is only divisible by 1 and 17, so it is a prime number.
Continuing to 18:
- 18 is divisible by 2, 3, 6, 9, and 18, so it is not a prime number.
Next is 19:
- 19 is only divisible by 1 and 19, so it is a prime number.
Lastly, we have 20, 21, 22, 23, 24, and 25:
- 20 is divisible by 2, 4, 5, 10, and 20, so it is not a prime number.
- 21 is divisible by 3, 7, and 21, so it is not a prime number.
- 22 is divisible by 2, 11, and 22, so it is not a prime number.
- 23 is only divisible by 1 and 23, so it is a prime number.
- 24 is divisible by 2, 3, 4, 6, 8, 12, and 24, so it is not a prime number.
- 25 is divisible by 5 and 25, so it is not a prime number.
Based on this analysis, the prime numbers between 15 and 25 are 17 and 23.
