The GCD of given numbers is 4.
Step 1 : Place the numbers inside division bar:.
| 36 | 56 |
Step 2 : Divide numbers by 2.
| 2 | 36 | 56 |
| 18 | 28 |
Step 3 : Divide numbers by 2.
| 2 | 36 | 56 |
| 2 | 18 | 28 |
| 9 | 14 |
Step 4 : Number 9 and 14, cannot be divided any more. The GCD is:
$$ GCD = 2\cdot2 = 4 $$This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
