Find Greatest Common Divisor of 90 and 1, using Euclidean algorithm.
Answer
The GCD of given numbers is 1.
Explanation
Step 1 :
Divide $ 90 $ by $ 1 $ and get the remainder
The remainder is zero => GCD is the last divisor $ \color{blue}{ \boxed { 1 }} $.
We can summarize an algorithm into a following table.
| 90 | : | 1 | = | 90 | remainder ( 0 ) |
| GCD = 1 | |||||
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
