For example, let's say we want to find all of the positive factors of $60$. You start by saying $1 \times 60 =60$ and make the gap between the two multiplied numbers smaller and smaller until you find all of them (see below):</p>
<p>$$1 \times 60$$</p>
<p>$$2 \times 30$$</p>
<p>$$3 \times 20$$</p>
<p>$$4 \times 15$$</p>
<p>$$5 \times 12$$</p>
<p>$$6 \times 10$$</p>
<p>And we found all of them! Pretty nifty. </p>
