210
The smallest factor is 1 because 3 is a prime number making its only factors 3 and 1.
2 and 3 are the smallest prime numbers. So answer is 2^3 * 3^3 = 216

It is 2 × 3 × 5 × 7 × 11 = 2310
The smallest positive integer is 3.
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).
Since 3 is prime, the factors are 1 and 3.
It is: 30
How about: 105
The prime factors of 315 are 3, 3, 5, and 7. To find the prime factors, you can start by dividing 315 by the smallest prime number, which is 2, but since 315 is odd, you move on to the next smallest prime number, which is 3. Dividing 315 by 3 gives you 105, and then further dividing by 3 gives you 35. Finally, dividing 35 by 5 gives you 7, which is a prime number. Therefore, the prime factors of 315 are 3, 3, 5, and 7.
