To calculate this interesting number you need to use the five smallest prime numbers. A Prime number is one which is not evenly divisible by any other number (except itself and 1). The first prime number is 2. then we have 3, 5, 7, 11, 13, 17 and so on. So, if you multiply 2 x 3 x 5 x 7 x 11 you'll get the smallest number with 5 different prime factors.
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
1155
30,030 Factorization: 2x3x5x7x11x13
The smallest number with 4 different prime factors can be found by multiplying the first four prime numbers together. These prime numbers are 2, 3, 5, and 7. Multiplying them together gives us 2 x 3 x 5 x 7 = 210. Therefore, 210 is the smallest number with 4 different prime factors.
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
The smallest number with 4 different prime factors can be found by multiplying the first four prime numbers together. These prime numbers are 2, 3, 5, and 7. Multiplying them together gives us 2 x 3 x 5 x 7 = 210. Therefore, 210 is the smallest number with 4 different prime factors.
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.
