Given:
The given numbers are 40 and 42.
Required:
We gave to find the GCD of the given numbers.
Explanation:
To find the GCD of the given numbers we have to find the factors of the given numbers.
[tex]40=2\times2\times2\times5[/tex][tex]42=2\times3\times7[/tex]The GCD means the greatest common factor. And we can see that only one 2 is present in both the factors. So the required GCD is 2.
Final answer:
Hence the final answer is 2.
