Answer:
Option A
Step-by-step explanation:
For finding the greatest common factor of 20 and 38
We will have to make factors of both terms first,
So,
factors of 20:2*2*5
factors of 38=2*19
It can be seen that there is only one common factor between the factors of the two terms which is 2.
So the Greatest common factor of both the terms will be 2.
Hence, the correct answer is Option A ..
