1. Factorise 72 and 90. 2 Find the greatest common factor. 3. Divide both, 72 and 90 by their gcf. So, 72 = 2*2*2*3*3 90 = 2*3*3*5 and their gcf = 2*3*3 Then 72/gcf = 2*2 = 4 and 90/gcf = 5 So 72/90 = 4/5
It is: 18
The GCF is 9.
The GCF is 18.
The GCF is 18.
GCF(25, 90, 135, 72) = 1.
The GCF is 9.
The GCF is 3.
The greatest common factor (GCF) is: 9.
The GCF is 9.
GCF(72, 27) = 9
The GCF is 6.
The GCF is 9.
The GCF is 2.
