The number 6. Its prime factors are 1,2 & 3
* * * * *
Most mathematicians would argue that the correct answer is 2*3*5 = 30 on the grounds that 1 is NOT a prime.

The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
How about: 105

30,030 Factorization: 2x3x5x7x11x13
210 with factors of 2, 3, 5, and 7
The smallest prime factors are 2,3,5,7 thus the smallest number would be the product of these will be 210
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).

5 and 11
30,030 Factorization: 2x3x5x7x11x13
If a number has 5 factors then it most certainly is not prime. Hence there is some confusion as to what you are asking here.

The smallest number with three different prime factors is 30.
Just multiply the first three prime numbers together.
