30 or 40
30
It is 30.
30
Multiples of 50 that are less than 200 are 100 and 150.
2 x 3 x 5 = 30
It's a multiple of 5, a multiple of 6 (since it's between twin primes), and less than 50. The only possibility is 30. To check: The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30
It is: 48
48 has 10 factors, the most factors of any number under 50.
No factors of 5 and 9 are greater than 5 and 9, respectively. 90 is a multiple of 5 and 9 in that range.
15, 30, 45
4*12 = 48
