if l is the least positive integer that is divisible by every integer from 1 to 9 inclusive , then l / 2 is =
the integer should be divisible by : 2 , 3 , 4 , 5 , 6 , 7 , 8 and 9 , that is 2 , 3 , 2 ^ 2 , 5 , 2 * 3 , 7 , 2 ^ 3 and 3 ^ 2 . the least common multiple of these integers is the product of 7 , 5 , 3 ^ 2 and 2 ^ 3 . then , l / 2 is ( 7 * 5 * 3 ^ 2 * 2 ^ 3 ) / 2 = 7 * 5 * 9 * 4 = 1260 . answer : d .
divide(multiply(multiply(multiply(power(2, add(2, 1)), power(add(2, 1), 2)), add(add(add(2, 1), 2), 2)), add(add(2, 1), 2)), 2)
