235 (number)
Encyclopedia
235 is the integer after 234 and before 236.
235 is the concatenation of the base 10 representations of the first three primes, and thus it is a Smarandache–Wellin number.
235 is from the subset of numbers that have exactly two nontrivial prime factor
s, neither of which is two or three, namely 235 = 5 X 47. Thus, 235 is also a square-free number.

Prime factor
In number theory, the prime factors of a positive integer are the prime numbers that divide that integer exactly, without leaving a remainder. The process of finding these numbers is called integer factorization, or prime factorization. A prime factor can be visualized by understanding Euclid's...
