What is a Prime Number?
A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In simpler terms, it has exactly two distinct positive divisors: 1 and the number itself.
Checking the Numbers
- 101: The only divisors of 101 are 1 and 101. Therefore, it is a prime number.
- 251: Similarly, the only divisors of 251 are 1 and 251, confirming that it is also a prime number.
Final Thoughts
Both 101 and 251 are prime numbers, as they meet the criteria of having no divisors other than 1 and themselves.
