The sum of an odd number of odd numbers will be odd.
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.
45 has only one number and that is 45. It is odd so 45 has one odd number.
The number is 105 (3 x 5 x 7). The next number that is the product of 3 odd primes is 165 (3 x 5 x 11).
27 is an odd number.
