Question

A courtyard has three walls with widths

Answer 1

Using the greatest common factor, it is found that the greatest dimensions each tile can have is of 3 feet.

---------------------------

• The widths of the walls are of 27 feet, 18 feet and 30 feet.
• The tiles must fit the width of each wall, thus, the greatest dimension they can have is the greatest common factor of 27, 18 and 30.

To find their greatest common factor, these numbers must be factored into prime factors simultaneously, that is, only being divided by numbers of which all three are divisible, thus:

27 - 18 - 30|3

9 - 6 - 10

No numbers by which all of 9, 6 and 10 are divisible, thus, gcf(27,18,30) = 3 and the greatest dimensions each tile can have is of 3 feet.
