<span>The GCF is the number that is a factor of both (or all) of the numbers of a given set and which is the biggest factor of this kind (often the smaller number of the two)
7 and 14 have a greatest common factor of 7.
 28 and 7 also have a GCF of 7, so the first two responses fit. 
21 and 3 have a GCF of 3, so that isn't correct. 
7 and 1 have a GCF of 1, so that's incorrect as well.</span>

Each Exterior Angle = Each Central Angle = (360 degrees) ÷ (Number of Sides)
</span>Each Exterior Angle = <span>(360 degrees) ÷ (Number of Sides)
</span><span>(Number of Sides) = 360 / 36
</span><span>Number of Sides = 10
