There are 19 multiples of five that fall between 1 and 100: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95.
The LCM is 1155.

There are no multiples of both 28 and 16 that fall between 55 and 101.
The integers between 5 and 150 inclusive that are multiples of 5 are: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150.
No number between 55 and 101 is a multiple of 410, though some are multiples of 20. 60, 80 and 100 are the multiples of 20 in that range, but none of them are multiples of 410. So no number between 55 and 101 is a multiple of 410 and 20.
