For anyone who found this thread by Google, or anyone else who is 
interested, the function is divisors().

Thanks. But this function gives only prime factors. Is there any
function which gives
all divisor?

One can get the number of factors by using 'len' on the result of this or
in tuples form by using 'list':

sage: len(factor(372))
3
sage: list(factor(372))
[(2, 2), (3, 1), (31, 1)]

[sage-support] Factors of an integer

[Santanu Sarkar]

Is there any function in Sage by which I can get the
number of prime factors,  number of factors of a
positive ineger?
