All the Prime Numbers from 0 to 100
A prime number is a whole number greater than 1 that has only two divisors: 1 and itself.
Here are all the prime numbers from 0 to 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
Why is 1 not a prime number?
While 1 is only divisible by 1 and itself, it doesn't fit the definition of a prime number because it has only one divisor, not two.
Let's understand how to identify prime numbers:
- Start with 2: 2 is the smallest prime number.
- Check divisibility: For each number from 3 to 100, check if it is divisible by any number smaller than it (excluding 1).
- Prime or not? If a number is only divisible by 1 and itself, it is a prime number.
Example:
- 13: 13 is only divisible by 1 and 13, so it's a prime number.
- 12: 12 is divisible by 1, 2, 3, 4, 6, and 12, so it's not a prime number.
Understanding prime numbers is essential in mathematics and has applications in various fields, including cryptography.
