9 x 8 x any number = 72 x any number

2 x 9 x 4 = 72

the second one the FINAL answer is 72

the first one will be higher

if you multiply 72 by any other number but 1, because 72 x 1 = 72, then they will be equal

but if any number is greater than 1, then the first will be higher

I hope you can understand

but ....

what if the "any other number " is a proper fraction?

so the "any other number" has to be > 1
