Yes.
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).
As a product of its prime factors: 3*7*7 = 147
As a product of its prime factors: 3*7 = 21
The smallest odd prime number is 3. The product of 13 and 3 is 39. 13 x 3 = 39
The prime factors for 1410 are: 2, 3, 5, 47 Smallest prime factor: 2 Largest prime factor: 47
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210

Yes.
It is 7 because as the product of its prime factors they are: 7*151*223 = 235,711
It is 11 and as a product of its prime factors: 5*5*11 = 275
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).
2 x 47 = 94
