Prime Numbers: In mathematics, there are many different types of numbers. One type of number that is an interesting area of study in math is a prime number. These numbers are defined as integers that are greater than or equal to 2 that are only divisible by 1 and themselves. ...
Only need to check primes less than √(23)23 is not divisible by 2or 3therefore 23 is prime orchecks all possible factors orchecks more factors than ecessary but argument must be complete. √(23)≈4.8 so only need to check 2 and 323 is odd so no need to check 223 is not a ...
