Find Greatest Common Divisor of 663 and 39, using Euclidean algorithm.
Answer
The GCD of given numbers is 39.
Explanation
Step 1 :
Divide $ 663 $ by $ 39 $ and get the remainder
The remainder is zero => GCD is the last divisor $ \color{blue}{ \boxed { 39 }} $.
We can summarize an algorithm into a following table.
| 663 | : | 39 | = | 17 | remainder ( 0 ) |
| GCD = 39 | |||||
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
