        <h2><a href="https://en.wikipedia.org/wiki/Venn_diagram">Venn Diagram</a> to calculate GCF & LCM of two numbers</h2>
Prime factors of 24 are in Set A.  Prime factors of 39 are in Set B.<br>
The GCF of 24 & 39 is in both Set A & B which is 3<br>
LCM of 24 & 39 is 2*2*2*3*13 = 312 or 2^3 * 3^1 * 13^1 = 312<br>
LCM = GCF * Remaining Prime Factors<br><br>
