The GCD of given numbers is 1013.
factors of 1013 are : | 1 , 1013 |
factors of 11143 are : | 1 , 11 , 1013 , 11143 |
factors of 112443 are : | 1 , 3 , 37 , 111 , 1013 , 3039 , 37481 , 112443 |
We see that the Greatest Common Factor = 1013.
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
