17 - 9 = 8
98. It's less than 100, and 9 + 8 = 17
17 is a deficient number because half the sum its factors is less than 17 [(1 + 17)/2 = 9)]. All odd numbers less than 945 are deficient.
8n - 9 = 17

To total 17 the two digits must be 8 and 9! The original number was 98.
3 less than the product of 9 and a number
No. A common multiple is a multiple of both numbers. There is no multiple of 17 that is less than 17.
No, it cannot. The LCM (least common multiple) is the lowest number that both numbers go into evenly. Since 17 cannot to into any number lower than itself, the LCM must be larger than 17.In this case, the least common multiple of 9 and 17 is 153.
