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

The main generalization you can make about all multiples of 5 would be that they will either end in the digit 0 or 5. So 5, 487975, 100, and so on all are multiples of 5. I don't believe there are any other generalizations that can be made about it.
To determine the factors of 100 that are multiples of 5, we first find the factors of 100, which are 1, 2, 4, 5, 10, 20, 25, 50, and 100. Among these factors, the multiples of 5 are 5, 10, 20, 25, 50, and 100. Therefore, there are 6 factors of 100 that are multiples of 5.
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, ....
20,40,60,80,and 100
5,10,15,20,25,30,35,40,45,50,55,60
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.
100, 200, 300, 400, 500
The highest power of 25 that divides the product of the first 100 multiples of 5 is 50. This is because for each multiple of 25, we have an extra factor of 25. Since there are 4 multiples of 25 in the first 100 multiples of 5, we have a total of 50 factors of 25.
