The greatest common factor (GCF) of 180 and 450 is 90.
The greatest common factor (GCF) of 15, 30, 90 is 15.
90+x+72+30 = 180. If you add 90+72+30, you get 192. But to get 180 you have to subtract 12. 90+(-12)+72+30 =180 if x is -12
78 is an acute angle as it is less than 90, 144 is an obtuse angles as it is between 90 and 180
The GCF is 30.
30
The GCF of 60 and 90 is 30.
The greatest common factor of the numbers 180 and 150 is 30.
The greatest common factor (GCF) of 180 and 450 is 90.
The GCF is 90.
90 and 180 have a GCF of 90.
90
The GCF of 90, 120 and 180 is 30.
If you mean 90, 120 and 180 then the GCF is 30
That cannot be determined. The GCF of 1, 2 and 87 is 1. The GCF of 15, 30 and 45 is 15. The GCF of 90, 180 and 270 is 90 on the chance that that is what you meant to ask.
The GCF is 6.
