Prime numbers are only divisible by two unique factors: the number 1 and the Prime number itself.
In mathematics, a prime number (or a prime) is a natural number which has exactly two distinct natural number divisors: 1 and itself. The first twenty-six prime numbers 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, 101.
Notice that these numbers are not divisible by 2 or any other number EXCEPT the number one and the number itself.
For example, 23 is only divisible by 1 (which 23/1 = 23) and the number 23 (which 23/23 = 1).

a prime number is a number that only has 2x tables as in 1 it only in the 1x table but so is number 2 and number 2 is the only even prime number
if you look at number 5 it is in the 1x and 5x so check the rest of the numbers
1 2 3 5 7 9 11 13 15 17 19 21 23 25 27 29 31 33 35 37 39 41 43 45 47 49 51 53 55 57 59 61 63 65 67 69 71 73 75 77 79 81 83 85 87 89 91 93 95 97 99 some of them are not prime numbers like 27 is in the 1x 3x 7x 27x so check them like that x abbey
