Answer:

1.8 and 12

Common factor is 4

multiplies of 8 is 2,4,and 8 by it self

multiplies of 12 is 2,3,6

2. 20 and 30

Common Factor is 10

multiplies of 20 is 2,4,5,and 10 its up to you what number you want to make as your awnser becase this muliplies of 20 are correct

multiplies of 30 is 3,5,6,and 10

3.16 and 24

Common factor is 8

Multiplies of 16 is 8 2 and 4

Multiplies of 24 is 8 2 and 4

4.9 and 12

Common factor is 3

Multiplies of 9 is 1 3 and 9 by it self

Multiplies of 12 is 2,3,4,6, and 12 by it self

5. 12 and 16

Common factor is 6

Multiplies of 12 is 2,3,4,and 6

Multiplies of 16 is 2,4,and 8

Ok so why are you all wondering why is this easy for me and how did i find many multiplies so you know how to multiply right but thats not all you have to try all number like from 2,to 10 to find your awnser and if the given numbers are in the same mulitple you have to write which is the biggest number and thats how you find the common factor and also i only added 1 because it is correct like example 8x1 is still 8 because you cant add from 8x1 because it stays at the same number if you multiply numbers with one that dosent change anything but if you raise more like 2 3 4 5 6 7 8 9 10 maybe you will find which multiple is the highest and also you should never forget the multiplycation table

you need that so that you can find the multiplies of the give number and remember to find the common factor always find the biggest number just like i did and also everyone never forget this just to let you know this is important.
