The GCF is 30.
The GCF of 90 and 180 is 90.
It is: 20
7
Their gcf is 15 .
The GCF of 60 and 120 is 60.
The GCF would be 10.
Since 20 is a factor of 60, it is automatically the GCF.
The GCF is 5.
90 you cant do 60-90 but you can do 90-60
90 + 90 + 60 = 240
The result of the equation - 90 plus 90 plus 60 plus 80, is found as follows; 90 + 90 + 60 + 80 = ( 90 + 90 ) + 60 + 80 = 180 + ( 60 + 80 ) = 180 + 140 = 320 Answer = 320
90-30 = 60
