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).

The smallest number is 504. There are no common factors other than 3x3, 2x2x2, and 7, so they must be multiplied together.
The greatest common factor must be a factor of the smallest number. The smallest number is 7. Its factors are 1 and 7. So the greatest common factor must be either 1 or 7. Since 7 is the larger of the two factors, check whether it is a factor of the additional numbers. Since it is, 7 is the greatest common factor.
70 is the smallest number that has prime factors of 2,5 and 7
If you mean 2, 3 and 7 as factors then the smallest number is 42
There are none but the smallest 3 digit number is 161
Well, darling, the smallest number with 2, 5, and 7 as prime factors is 70. You see, 2 x 5 x 7 equals 70, and that's the tiniest number you can whip up with those prime factors. So, there you have it, sweet cheeks, the answer is 70.

Well, honey, the smallest number with prime factors 3, 5, 7, and 11 is simply the product of these primes: 3 * 5 * 7 * 11 = 1155. So, there you have it, darling, 1155 is the smallest number you're looking for.
It is 7 because as the product of its prime factors they are: 7*151*223 = 235,711

It is 2^6 = 64.
