How to solve by long division method, if you wanna find LCM

To find the LCM you must find all factors of the numbers, and then multiply all the factors together including the ones that are not shared among the numbers.

For example,

Factors of 10: 2×5

Factors of 30: 2×3×5

LCM of 10 and 30: 2×3×5 = 30

However do note not to multiply a factor more than once if it is shared among two numbers.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
