Factors

The factors of a number are the row lengths that make a rectangle of it: 12 chairs make rows of 1, 2, 3, 4, 6 or 12, so those are the factors of 12. They come in pairs (3 × 4 = 12), and the pairs meet in the middle.

Depth 1 · Foundation

You can find all the factors of a number as rectangles or factor pairs, stop when the pairs turn round, and know every number has 1 and itself as factors.
