Question

what is the meaning of prime numbers ? ​

Answer 1

Answer:

a number that is divisible only by itself and 1 (e.g. 2, 3, 5, 7, 11).

Answer 2

Answer:

The first 25 prime numbers (all the prime numbers less than 100) are: 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 (sequence A000040 in the OEIS). . Therefore, every prime number other than 2 is an odd number, and is called an odd prime.

For example, the first 5 prime numbers are 2, 3, 5, 7, and 11. By contrast, numbers with more than 2 factors are call composite numbers.
