Prime Number
A prime number can be divided evenly only by \(\large{ 1 }\) , or itself and it must be a whole number greater than \(\large{ 1 }\) .
- \(\large{\; 1 }\) is a prime number because only \(\large{ 1 }\) and \(\large{ 5 }\) divide \(\large{ 5 }\) evenly.
- \(\large{\; 9 }\) is not a prime number because \(\large{ 3\;x\;3=9 }\) .
- The first ten prime numbers are: \(\large{ 2,\; 3,\; 5,\; 7,\; 11\;, 13,\; 17,\; 19,\; 23,\; 29,\; ... }\)
- There is no pattern or formula for counting indefinitely by primes.
