The fundamental theorem of arithmetic states that any number can be factored to a set of primes. Using prime numbers up to the square root of a number can be used to determine if a number is prime or composite. The square root of 100 is 10. SO using the prime numbers 2,3,5, and 7, a student can determine if a number is prime or composite. After this exercise the students are ready to use 2,3,5, and 7 for a variety of other math operations. e.g., reducing fractions to lowest terms and knowing
