10
It is 11 which is a prime number whose factors are itself and one
Starting from beginning we see that 0 has infinite factors so it is a composite number and 1 is neither prime nor composite. The next number is 2 which has only two factors so it is the smallest Prime number.
the answer would seem to be ten.
If you mean 2, 3 and 7 as factors then the smallest number is 42
114
36
70 is the smallest number that has prime factors of 2,5 and 7
8, 2*2*2
stupid
