Question 11823
well, assuming 1 is not a prime number, then the primes are 2,3,5,7,11,13, etc


4 smallest are 2,3,5,7.

Multiply these together, you get 210.
So it is impossible to have a number less than 210 that has 4 prime factors. And this also means that no number less than 210 can be divided by 4 primes.
