8 and 9 do not "go into" each other in the traditional sense as they are both prime numbers and do not have any common factors other than 1. However, if you are asking what numbers can be evenly divided by both 8 and 9, the least common multiple of 8 and 9 is 72. Therefore, any multiple of 72, such as 72, 144, 216, etc., can be evenly divided by both 8 and 9.
They both go into 1440, for example.
72
8 x 9 x 10 = 720
The lowest common multiple of 9 and 8 is 72.
6 goes in 12 times. 8 goes in 9 times. 9 goes in 8 times.
9 can go into 72 8 times. (72 / 9 = 8)
They both go into 1440, for example.
7 goes into 56 8 times56 / 7 = 8
80 ÷ 9 = 8 with remainder 8
9+9-9/.9=8 here u go
Not evenly.
72
9 x 8 = 72
8 x 9 x 10 = 720
79/9 = 8 and 7/9

They can go into 8*4*9 = 288. That is not the smallest such number, but that was not the question.
