6r2-87r+270 = (2r-9)(3r-30) when factored
Since 45 is a factor of 270, it is automatically the GCF.
The greatest common factor of 270 and 360 is 90.
130 + 290 + 270 = 690
the highest common factor of 225 and 270 is: 45
10
Greatest common factor of 140 and 270 is 10.
10/270 + 15/270 + 27/270 = 52/270 = 26/135
GCF(270, 200) = 10
Since 45 is a factor of 270, it is automatically the GCF.
It is any number that is not a factor of 270
