The GCD of given numbers is 24.
Step 1 :
Divide $ 48 $ by $ 24 $ and get the remainder
The remainder is zero => GCD is the last divisor $ \color{blue}{ \boxed { 24 }} $.
We can summarize an algorithm into a following table.
48 | : | 24 | = | 2 | remainder ( 0 ) |
GCD = 24 |
This solution can be visualized using a Venn diagram.
The GCD equals the product of the numbers at the intersection.
