The GCD of given numbers is 25.
factors of 75 are : | 1 , 3 , 5 , 15 , 25 , 75 |
factors of 100 are : | 1 , 2 , 4 , 5 , 10 , 20 , 25 , 50 , 100 |
We see that the Greatest Common Factor = 25.
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
