The GCD of given numbers is 1.
factors of 45 are : | 1 , 3 , 5 , 9 , 15 , 45 |
factors of 83 are : | 1 , 83 |
factors of 79 are : | 1 , 79 |
We see that the Greatest Common Factor = 1.
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
