Find this number (Posted on 2016-04-04) Difficulty: 2 of 5
Every composite number N can be represented by a product of k (k>1) primes, not necessarily distinct, N=p1, p2, p3, … plast, e.g. 28=2*2*7.
In this case, the sum of al primes from the smallest to the last, including both is 2+3+5+7=17, which differs from the number 28.

What is the smallest composite number that equals the inclusive sum of the primes from its smallest to the largest prime factor, including both ?

How many additional numbers, displaying the said feature exist below 200?
