The sum of three odd numbers gives an odd
number

So, the sum of 3 given odd numbers doesn’t results 30

So, it is an impossible factor

here we can't use 3! too

because 3! [3×2×1] results a even number 6

so we can’t use it.

If there will be an allowance of factorials, then the answers will be

3! + 15 + 9 =30

3! + 11 + 13 = 30
