The GCD of given numbers is 9.
Step 1 : Place the numbers inside division bar:.
| 5436 | 675 |
Step 2 : Divide numbers by 3.
| 3 | 5436 | 675 |
| 1812 | 225 |
Step 3 : Divide numbers by 3.
| 3 | 5436 | 675 |
| 3 | 1812 | 225 |
| 604 | 75 |
Step 4 : Number 604 and 75, cannot be divided any more. The GCD is:
$$ GCD = 3\cdot3 = 9 $$This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
