I didn't get such answer as you got,my Sage factor 2007193456621 correctly.
N.factor() returns 1001797*2003593.
Did you use an old version of Sage?

I use Sage 6.1.1 which I build from source code on my x86 Ubuntu14.04

Thank you,Kcrisman.
I am so sorry that I did not ask my question clearly, but luckly you understand
most of my question.
The link to publication that use sage is great.
I do hope sage can have a lot of packages like R.
It seems that sage focus on pure mathematics more than application.I do not
fi
In fact,I like the pure math part of sage.But it would be better if I can do
some modelling on sage.
Recently I was reading the reference manual of probability, but I found that
RealDistribution does not support normal distribution.
RealDistribution supports uniform, gaussian,rayleigh,lognormal,
I am so sorry that I forget about this as the 'gaussian'distribution in sage
only take one parameter sigma. I think 'normal' distribution should have two
parameters mu and sigma.

Thanks a lot.I was learning how to use R in Sage recently.
The norm function of R provides a normal distribution of two parameters mean
and sd.So I would use the R interface in Sage instead.
But I have problem ploting wuth R interface in Sage.
I use the folliwing code to plot a histogram hut faile
I want to use FiniteDimensionalAlgebra to check if a given table of
multiplicayion can form a associative algebra. But the function
FiniteDimensionalAlgebra do not check for association.
Code is as below.
##
FinitDimensionalAlgebra(CC,[Matrix([[1,1],[1,0]]),Matrix([[0,1],[1,1]])])

Thank you,Peter.
I have another stupid question that does not related to this topic, I think it
difficult to write a matrix as a list of list in Sage.And it is confused that
matrix is immutable that I cannot modify the element of a matrix.
Is there some smart way to define and use a matrix in Sag
I use the following code but failed.
###
x=[1,2,3,4,5]
y=[2,3,4,5,6]
x=r(x)
y=r(y)
r.t_test(x,y,alternative="less")
###
It returns that error:object 48 not found
But it works if I didn't use alternative.
r.t_test(x,y) will return the result of two sid
