Find the largest three digit number that can be halved at least 8 times.

Ok so to do this we need to start with 1 and multiply it by 2 8 times to get our answer, therefore we have 2*2*2*2*2*2*2*2=256

We can show this as:

256/2=128 (1)

128/2=64 (2)

64/2=32 (3)

32/2=16 (4)

16/2=8 (5)

8/2=4 (6)

4/2=2 (7)

2/2=1 (8)
