1 x 100 = 100
2 x 100 = 200
3 x 100 = 300
4 x 100 = 400
5 x 100 = 500
100, 200, 300, 400, 500
The multiples of 5 that are also multiples of 6 are multiples of their LCM. The LCM of 5 and 6 is 30, so the question becomes which multiples of 30 are less than 100? The solution is the numbers: 30, 60, 90

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.

There are an infinite number of multiples of 100. 100, 200, 300,400, ....
5, 10, 15 and just keep adding 5 until you get to 100.
100, 200, 300, 400, 500.
If 100-300 is inclusive, the answer is 41.
