The number of ways 105 can be written as a sum of two or more consecutive positive integers = number of odd divisors of 105 -1 = 8 - 1=7 |

hi for the second question the explanation is 55! factorial definitely consists of multiples of 9 so any number which is a multiple of 9 should have the digits sum as 9 |
