The GCD of given numbers is 3.
factors of 102 are : | 1 , 2 , 3 , 6 , 17 , 34 , 51 , 102 |
factors of 351 are : | 1 , 3 , 9 , 13 , 27 , 39 , 117 , 351 |
We see that the Greatest Common Factor = 3.
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
