# 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.
