105=3*5*7it has to be only three factors and they are all prime105
The answer is 105 because 3,5, and 7 are all prime factors and when you multiply the numbers together it comes out to be 105 witch is lower than 160 and is an odd number.
By definition, a prime number has exactly two factors. So, there are no prime numbers with exactly three factors.
