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