The smallest number divisible by first four prime numbers is 2x3x5x7 = 210.
The smallest four prime numbers are 2, 3, 5, 7, and their sum happens to be a prime.
The sum of the five smallest prime numbers is 18.
The smallest composite numbers are 4, 6, 8, 9, and 10. It should be noted that the number 1 is a unit, and is neither prime nor composite. The numbers 2, 3, 5, and 7 are all prime, leaving the remaining numbers as the 5 smallest composites.
Multiply the 4 smallest prime numbers... 2 X 3 X 5 X 7 = 210
The smallest number divisible by first four prime numbers is 2x3x5x7 = 210.

Because the four smallest prime numbers are 2, 3, 5, and 7. If you multiply these four together you get 210 (which makes 210 the smallest number divisible by four unique prime numbers).
The sum of the five smallest prime numbers is 18.

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).
There isn't one. Negative numbers have prime factors and numbers don't stop. The smallest positive numbers with a prime factor is 2.
The smallest composite numbers are 4, 6, 8, 9, and 10. It should be noted that the number 1 is a unit, and is neither prime nor composite. The numbers 2, 3, 5, and 7 are all prime, leaving the remaining numbers as the 5 smallest composites.
2 is the smallest prime number. 11 and 97 are the least and greatest two-digit prime numbers.
Many prime numbers and many composite numbers.
