z1=25; z2=20; z3=70;
z4=32; z5=19;
z6=32; z7=19
Multiplicity of the planetary gear
k1=z3/z1=70/25
k2=z3/z4=70/32
k3=z3/z6=70/32
Gear ratio
1-th stage
u1=1+k1=1+(70/25)=4.5
2-th stage
u2=1+k2=1+(70/32)=51/16≈3.188
3-th stage
u3=1+k3=1+(70/32)=51/16≈3.188

Total
First output
u=u1=4.5
Second output
u=u1*u2*u3=4.5*51/16*51/16=23409/512≈45.721
