how many of the positive divisors of 600 are also multiples of 4 not including 600 ?
"600 = 2 ^ 6 * 3 * 5 = ( 4 ) * 2 * 3 * 5 ^ 2 besides ( 4 ) , the exponents of 2 , 3 , and 5 are 1 , 1 , and 2 . there are ( 1 + 1 ) ( 1 + 1 ) ( 2 + 1 ) = 12 ways to make multiples of 4 . we must subtract 1 because one of these multiples is 600 . the answer is d ."
divide(divide(divide(600, 4), const_2), const_3)
