if x , y , and z are positive integers , and 4 x = 5 y = 8 z , then the least possible value of x + y + z is
"take lcm of 4,5 and 8 = 40 now 4 x = 40 = > x = 10 5 y = 40 = > y = 8 8 z = 40 = > z = 5 10 + 8 + 5 = 23 . option b ."
add(add(divide(divide(multiply(multiply(4, 5), 8), const_2), 4), divide(divide(multiply(multiply(4, 5), 8), const_2), 5)), divide(divide(multiply(multiply(4, 5), 8), const_2), 8))
