question: can any can show what we can do when order of curve is factoring?

i mean example of break of curve
here curve

Code:
p=1329227995784915872903807060280346673
n=1329227995784915873774466533394260857 

E = EllipticCurve(GF(p), [0, 7])

x=30507442907313187558766756674287563 
y=6808648889992806182135164899320444 
G = E.point((x,y))

print("factor_of_order",factor(n))




n= 31 * 38707 * 45058303062757 * 24585182790148153 == 1329227995784915873774466533394260857
