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.

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.
36 is a composite number between 30 and 40 because its factors are 1,2,3,4,6,9,12,18,36
Any number between 30 and 40 can be a factor. The common factors of 30 and 40 are 1, 2, 5 and 10.
The numbers between 10 and 30 that have exactly 5 factors are 16 and 25. The number 16 has factors 1, 2, 4, 8, and 16. The number 25 has factors 1, 5, 25, but since it is a perfect square, it also includes the repeated factor of 5. These are the only two numbers between 10 and 30 that have exactly 5 factors.
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.
