The GCD of given numbers is 5.
| factors of 2345 are : | 1 , 5 , 7 , 35 , 67 , 335 , 469 , 2345 |
| factors of 180 are : | 1 , 2 , 3 , 4 , 5 , 6 , 9 , 10 , 12 , 15 , 18 , 20 , 30 , 36 , 45 , 60 , 90 , 180 |
We see that the Greatest Common Factor = 5.
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
