Step 2 : Put a box around factors that are common for all numbers:

$$\begin{aligned}184 =& \color{blue}{\boxed{2}}\cdot\color{red}{\boxed{2}}\cdot2\cdot\color{Fuchsia}{\boxed{23}}\\[8pt]460 =& \color{blue}{\boxed{2}}\cdot\color{red}{\boxed{2}}\cdot5\cdot\color{Fuchsia}{\boxed{23}}\\[8pt]\end{aligned}$$

Step 3 : Multiply the boxed numbers together:

$$ GCD = 2\cdot2\cdot23 = 92 $$

This solution can be visualized using a Venn diagram.

The GCD equals the product of the numbers at the intersection.
