<p><a href="https://www.prepswift.com/quizzes/quiz/prepswift-the-primes" target="_blank">The Primes Exercise</a></p><p>Primes are of course the &quot;building blocks&quot; of numbers in that every positive integer greater than $1$ can be &quot;broken down to its prime factors&quot; via prime factorization.</p> <p>And of course primes only have two positive factors: $1$ and itself.</p> <p>We recommend memorizing <strong><u>all</u></strong>&nbsp;primes from $1$ to $50$. There are $15$ of them.&nbsp;</p> <p>$$2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47$$</p>
