2 cubed is 8.3 cubed is 27.4 cubed is 64.5 cubed is 125.6 cubed = 216.7 cubed is 343.
Your sequence seems to be a cubed sequence, but you are missing 64 between 27 and 125.13 = 123 = 833 = 2743 = 6453 = 12563 = 216So, next would be 73, which equals 343.
5 x 5 x 5 = 125 7 x 7 x 7 = 343
5x5x5 gives us 125 7x7x7 gives us 343 343/125 is 2.744
The LCM is: 42,875
