Prime Number

Written by Jerry Ratzlaff on . Posted in Algebra

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.
