1, 2, 4, 8 1, 2, 4, 7, 14, 28
1, 2, 4, 7, 8, 14, 28, 56 | 1 x 56, 2 x 28, 4 x 14, 7 x 8.
If you mean 2 into 28 then it is 14 times
the answer for that is 4
6*9=54 so they both go into it evenly, but the lowest number is 18.
Their LCM is 1400
The number that both 7 and 8 can go into evenly is 56.
As 8 is even, and 3 is odd, I think only 1 can go into both.
The greatest common factor of 8 and 28 is 4, because 4 is the highest number that will divide into both evenly.

It is: 200
The LCM of 8 and 10 is 40
The number is 120.
Their HCF is 8
The LCM is 216
