1 and 18
6.
3, 6, 15, 30
I think 6, 12 and 18 would disagree with that.
The factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60. The odd composite factor is 15.
Which number is a factor of 10 , but not a multiple of 5
The answer is 9. It is a multiple of 3. 3+3+3=9. It is less than 20: 20-9=11.It is not a prime number. It is odd, and it is not a factor of 30. 30/9=3.3333333333
15 is all of those things.
All odd multiples of 3 are not factors of 8.
6.
9
a multiple of 3
3, 6, 15, 30
No. Double any odd number. The result is even.
There is no such number. If a multiple of 4 is a factor of 30, then 4 must also be a factor of 30, but 4 is not a factor of 30 (the factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30), thus no such number exists.
Any multiple of 30.
I think 6, 12 and 18 would disagree with that.
Any multiple of 30 has these factors.
