The GCD of given numbers is 2.
factors of 414 are : | 1 , 2 , 3 , 6 , 9 , 18 , 23 , 46 , 69 , 138 , 207 , 414 |
factors of 662 are : | 1 , 2 , 331 , 662 |
We see that the Greatest Common Factor = 2.
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
