Just count by three ... 3, 6, 9, 12 ,15, 18, 21, 24, 27 ... all the way to 99. There are 33 numbers in this list. 100 is not an even multiple of 3.
Way too many to list... 3 6 9 12 15 18 21 ...
Start counting from 2. For each number, if it has factors besides 1 and itself, then skip it; but if it doesn't have, then write it down. When you reach 10,000, you'll have the list, and you can count them. Here's another way to do it, which is probably easier: -- Write down all the numbers from 2 to 10,000. -- Start with 2. Cross all multiples of 2 off the list. -- Then go to 3. Cross all multiples of 3 off the list. -- 4 is gone ... it was a multiple of 2 ... so go on to 5. Cross all multiples of 5 off the list. -- 6 is gone ... it was a multiple of 2 and also of 3 ... so go on to 7. Cross all multiples of 7 off the list. -- 8, 9, and 10 are gone. Go on to 11. Cross all multiples of 11 off the list. -- Keep going like this, until you reach 5,000 . You'll have the list, and you can count them.

It's hard to do mathematical notation here, but:X : X E { X = 12N}; N E JIt's possible in theory to list all the multiples of twelve in the same way it's possible in theory to list all the integers.In practice, not so much.

Yes, it is infinite. All numbers are actually. For example, Let's say the teacher makes you post multiples from 2 to 50 you can go all the way to 50 and beyond actually. Just keep adding two.
List the numbers from 2 to 100. Rows of 10 work well. Cross out all the multiples of 2 that are greater than 2. This will be the rest of the even numbers. Go to the next number that isn't crossed out (3) and cross out all of its greater multiples. Proceed in this fashion. Next up will be 5. You can stop when you get to fifty. The numbers that aren't crossed out are prime.
I have this hunch that you're looking at a list of choices. Since you're not sharing the list, there's no way I can help you select the correct choice. There are an infinite number of common multiples of 12 and 10 . The smallest one is 60, and all the others are multiples of 60 .
