Answer 2

Answer: 10

Step-by-step explanation:

To find : The greatest common factor of 110, 40, and 120

We first write the prime factorization of 110, 40, and 120 as follows:

$110=2\times5\times11\\\\40=2\times2\times2\times5\\\\120=2\times2\times2\times3\times5$

From the above prime factorization, we can see that the greatest common factor of 110, 40, and 120 =$2\times5=10$

Hence, the greatest common factor of 110, 40, and 120 =10
