210=1024, which has factors of 2i with i between 0 and 10 inclusive.
Explanation
If the prime factorization of a number is p1a*p2b*p3c...
the number of factors is (a+1)*(b+1)*(c+1)... [because each pi can be raised to the 0, 1, 2,..., up through the exponent, so there are a+1 choices for the exponent of p1, b+1 choices for the p2, etc.]. But because 11 is prime, there can only be one pi that will yield exactly 11 factors [if, for example, there were two prime factors of the number, you would need (a+1)*(b+1)=11 but because 11 is prime, this won't work unless one of a or b is zero] . 2 is the smallest Prime number, and 210=1024 is the smallest whole number with exactly 11 factors.

What are factors and primes?
Factors are whole numbers that divide exactly into a whole number. These numbers have no remainder. Primes, on the other hand, have exactly two factors which are 1 and itself.
