The GCD of given numbers is 6.
Step 1 :
Divide $ 96 $ by $ 6 $ and get the remainder
The remainder is zero => GCD is the last divisor $ \color{blue}{ \boxed { 6 }} $.
We can summarize an algorithm into a following table.
| 96 | : | 6 | = | 16 | remainder ( 0 ) |
| GCD = 6 | |||||
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
