The GCD of given numbers is 4.
Step 1 : Place the numbers inside division bar:.
56 | 92 | 124 |
Step 2 : Divide numbers by 2.
2 | 56 | 92 | 124 |
28 | 46 | 62 |
Step 3 : Divide numbers by 2.
2 | 56 | 92 | 124 |
2 | 28 | 46 | 62 |
14 | 23 | 31 |
Step 4 : Number 14, 23 and 31, 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.
