For this, you want to find the Factors, the Common ones and then the Greatest of those.
*Always list factor in pairs so that none are missed/left out

First, Factors of 32
1, 32
2, 16
4, 8

Now, Factors of 81
1, 81
3, 27
9

The next step is to highlight/circle the common factors

1,

As there is only one common factor, that is the greatest.
The GCF is 1

In a flight of 600 km, the speed of the aircraft was slowed down due to bad weather. The average speed of the trip was decreased

UkoKoshka [18]

The average speed would be 600 km/hr.

Step-by-step explanation:

Let the original speed be 'x'

Let the decreased speed be 'x-200'

Distance = 600 km

Time increased by 30 minutes

According to question, it becomes,

$\dfrac{600}{x-200}-\dfrac{600}{x}=\dfrac{30}{60}\\\\\dfrac{x-(x-200)}{x^2-200x}=\dfrac{1}{2\times 600}\\\\\dfrac{200}{x^2-200x}=\dfrac{1}{1200}\\\\240000=x^2-200x\\\\x^2-200x-240000=0\\\\x=600,-400$
