The Greatest Common Factor (GCF) is: 270
30% of 2700= 30% * 2700= 0.3 * 2700= 810
The GCF of 72, 270 and 810 is: 18
810 metres or 2700 feet
180
The GCF is 54.
Since 18 is a factor of 810, it is automatically the GCF.
Their LCM is 2700/(15^2) = 180.
The GCF is 54.
The GCF is: 10
The GCF is 60.
27 and 486, respectively.
The GCF is 16.
