what number is not a prime factor
There are 12 composite (and 8 primes) in the first twenty whole numbers. So the probability of randomly choosing a non-prime is 12/20 or 60%.
You find the first 20 prime numbers and add them together. There is no formula for generating a sequence of prime numbers and so none for the series of their sums.You find the first 20 prime numbers and add them together.

what number is not a prime factor
2 is the first prime number.
The first prime number after 14 is 17.
There are 12 composite (and 8 primes) in the first twenty whole numbers. So the probability of randomly choosing a non-prime is 12/20 or 60%.
5 is the greatest prime factor of 20.
20 is not a prime number because 5 and 4 10 and 2 can also go into 20 not just 20 and 1
20 is a composite number
11 + 101 = 112
