if 7 ^ q is a factor of the product of the integers from 1 to 100 , inclusive , what is the largest value of q ?
so the question just means that we have to find all the multiples q of 7 between 1 to 100 so there are 14 multiples of 7 ( 7 - 98 ) but 49 and 98 contain two 7 ' s as factors so we have to add 14 + 2 = 16 e
add(divide(100, 7), divide(divide(100, 7), 7))
