The GCD of given numbers is 4.
Step 1 : Place the numbers inside division bar:.
88 | 220 |
Step 2 : Divide numbers by 2.
2 | 88 | 220 |
44 | 110 |
Step 3 : Divide numbers by 2.
2 | 88 | 220 |
2 | 44 | 110 |
22 | 55 |
Step 4 : Number 22 and 55, 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.
