    240,120,60,30, 15, 15/2, 15/4, 15/8 ( cannot have 15/16 as < 1)

    Hence 15/8

    Answer is 15/8

    It's simple

    240
    120
    60
    30
    15/2 = 7.5
    7.5/2 = 15/4 = 3.75
    3.75/2 = 15/8 = 1.875
    1.875/2 will be less than one. Hence the smallest possible number in this sequence is 15/8
