There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
The first three prime numbers are 2,3,5. The smallest number divisible by 2,3 and 5 is 30 (2*3*5).
The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
120
the answer is 120 because the first three prime numbers are 2,3,5 and the first three composite numbers are 4,6,8.
Just multiply the first three prime numbers together.
2,3, and 5.

53 is the smallest prime number that is larger than 50
2 is the smallest prime number. Numbers can't have factors larger than themselves. Zero and one aren't large enough to have prime factors.
154, 308, 462
The sum of the five smallest prime numbers is 18.
