56, 70, 84 and 98.
There are an infinite number of multiples of 100. 100, 200, 300,400, ....
They are: 55, 66, 77, 88, 99.
Since 10 is a multiple of 5, all multiples of 10 will also be multiples of 5. Test the theory. 30, 50, 100... All multiples of 10, and also of 5.

56,64,72,80,88,96
55,66,77,88,99
50, 60, 70, 80, 90, and 100.
56, 63, 70, 77, 84, 91, 98.
They are: 60, 75 and 90
There are 8 of them and they are all multiples of 12
There are 10 multiples of 10 between 1 and 100: 10, 20, 30, 40, 50, 60, 70, 80, 90, and 100.
56, 70, 84 and 98.
