b= 10
Not sure about the greatest commom factor, but the greatest common factor is b.
12b - 9 + 2b - b = -87 13b - 9 = -87 13b = -87 +9 13b = -78 b = -6
Re-ordering it : 13a - a -15b + 2b = 12a - 13b
15b+2-13 = 13b+6-4b 15b-11 = 9b+6 15b-9b = 6+11 6b = 17 b =17/6 or 2 and 5/6
LCM[(13b3)3, 7b2] = LCM[2197b9, 7b2] = 2197*7*b9 = 15379*b9
The primary difference between the 85 and 86 13B rotary engines lies in their design and performance characteristics. The 1985 13B features a simpler peripheral-port design, offering decent power but limited tuning potential. In contrast, the 1986 13B introduced a more advanced engine architecture, including a bridge-port configuration that enhances airflow, resulting in improved performance and responsiveness. Additionally, changes in engine management systems and emissions controls between these years also contribute to differences in efficiency and power delivery.
