Factorization Diagrams

Factorization Diagrams are graphical representations of numbers using dots clustered by their factors (as in the banner above). For instance, 105 = 3x5x7 and its diagram would be three groups of five heptagons in a pentagonal formation for a total of 105 dots. Each chart shows the first few hundred such diagrams. See more details on the back of each chart - freely downloadable.
