It is 2 × 3 × 5 × 7 × 11 = 2310
The smallest positive integer is 3.
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).
Since 3 is prime, the factors are 1 and 3.
It is: 30
How about: 105
