6. Factors are 1, 2, 3, and 6.
4 : with factors 1, 2 and 4
Let's call the number 'n'. Its factors will be 1, itself and an unknown number. It will need to be a perfect square, and after some trial and error, we will come to the conclusion that it is 1369. The factors are 1, 1369 and 37.
Logically, the smallest number with 4 different prime factors would have to be the product of the smallest four prime numbers. So the smallest natural number with four different prime factors is 210 (2*3*5*7).
