To find the greatest common factor of 40 and 27, we can first start by making a list of factors for each number.
The factors of 27 are: 1, 3, 9, 27
The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40
When looking at these numbers, we can see that 1 is the greatest common factor of both 40 and 27.
Consider the function
First, factor it:

1. From the attached graph you can see that
- function is positive for

- function is negative for

2. Since
the function is neither even nor odd.
3. The domain is
the range is
If you round it to the nearest pound it is 1.1 kg
