What is a prime number?
A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In other words, a prime number is a number that can only be divided evenly by 1 and itself. For example, the first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and so on. Prime numbers play an important role in number theory and have applications in various fields such as cryptography and computer science.
Definition of prime number
A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself. In other words, a prime number is a number that can only be divided evenly by 1 and itself. For example, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, and so on are all prime numbers. However, numbers like 4, 6, 8, 9, 10, 12, and 15 are not prime numbers because they have factors other than 1 and themselves (for example, 4 is divisible by 2).
Examples of prime number
Here are some examples of prime numbers:
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, 101, 103, 107, 109, 113, 127, 131, 137, 139, 149, 151, 157, 163, 167, 173, 179, 181, 191, 193, 197, 199, 211, 223, 227, 229, 233, 239, 241, 251, 257, 263, 269, 271, 277, 281, 283, 293, 307, 311, 313, 317, 331, 337, 347, 349, 353, 359, 367, 373, 379, 383, 389, 397, 401, 409, 419, 421, 431, 433, 439, 443, 449, 457, 461, 463, 467, 479, 487, 491, 499, and so on.
