31 and 37 each have two factors.
23 and 29 because they are prime numbers
12 is divisible by 2, 3, 4, and 6.
6, 8, 10, 14, 15
36
48
30 does.
Itself but if you mean 2, 3, 5 and 6 then it is 30
60 15 and 4 have no common factors, so the LCM must be at least their product. The number 30 does not introduce any additional factors, so the LCM is 60.
32 and 36 are numbers BETWEEN 30 and 40 that have 4 as a factor. 40 does also, if the range beween 30 and 40 was meant to be inclusive.

30
The factors of a number cannot be greater than the number itself. So there are no factors of 4 between 30 and 50.
That number is 36.
Any number between 30 and 40 can be a factor. The common factors of 30 and 40 are 1, 2, 5 and 10.
A number that has exactly an odd number of factors is a power of another number. A number between 10 and 30 that is a power is 16. It is 24 (as well as 42) and its factors are 1, 2, 4, 8, and 16.
36 is a composite number between 30 and 40 because its factors are 1,2,3,4,6,9,12,18,36
48 has 10 factors.
If you include 30, both 24 and and 30 have 8 factors, the most in that range.
36 has 9 factors.
20 and 28 both have six factors.
36 does.
Itself but if you mean 2, 3, 5 and 6 then it is 30
