The GCD of given numbers is 35.
Step 1 :
Divide $ 385 $ by $ 35 $ and get the remainder
The remainder is zero => GCD is the last divisor $ \color{blue}{ \boxed { 35 }} $.
We can summarize an algorithm into a following table.
| 385 | : | 35 | = | 11 | remainder ( 0 ) |
| GCD = 35 | |||||
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
