At a guess, it's because you want all the odd numbers.
There needs to be more information regarding the context of the multiples of 2 being crossed out if you want any more information in the answer.
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.

All multiples of 8 are also multiples of 2, but not all multiples of 2 are multiples of 8.
All multiples of 16 are also multiples of 2.
Yes, multiples of 8 are also multiples of 2 because 8 is a multiple of 2 itself.
2 has an infinity of multiples
the multiples of 2 are 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36.38,40,42,44,46,48,50,52,54,56,58,60,62,and so on
the multiples of 2 are 2,4,6,8,10,12,14,16,18,20,22,24,26,28,30,32,34,36,38,40,42,44,46,48,50,52,54,56,58,60,62,64,66,68,70,72,74,76,78,80,82,84,86,88,90,92,94,96,98,100
All the even numbers are multiples of 2
multiples of 8 are also multiples of 2 because anything you times by 8 is an even number
