What is this?

The Cann Heuristic is a visual tool for exploring the arithmetic properties of a number. It's not a perfect factorizer, but it often reveals a number's factors (or numbers that share factors) through geometric intersections.

How it's Calculated

Two sets of lines are drawn on a chart scaled from 0 to your input number (N) on both axes:

• Lower Lines (Blue): These lines start at (0, 0) and pass through points (p, 1), where 'p' is a power of two (1, 2, 4, 8...).
• Upper Lines (Pink): These start at (0, N) and are calculated to pass through points (p, N-p-1), again for each power of two 'p'.

What it Shows

The yellow dots mark where a blue line and a pink line intersect. The grid below shows the coordinates of these intersections, but only if the X or Y coordinate is a whole number. These specific points are often related to the factors of the input number.
