7.5 m3
11.5 m
1 m
4 m
28 m
2 m
3.5 m
15 m

11.5

Step-by-step explanation:I’ve done this in a test before and that is the correct AnSwEr

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18
