if x , y , and z are positive integers , and 2 x = 5 y = 6 z , then the least possible value of x + y + z is
"take lcm of 2,5 and 6 = 30 now 2 x = 30 = > x = 15 5 y = 30 = > y = 6 6 z = 30 = > z = 5 15 + 6 + 5 = 26 . option b ."
add(add(divide(divide(multiply(multiply(2, 5), 6), const_2), 2), divide(divide(multiply(multiply(2, 5), 6), const_2), 5)), divide(divide(multiply(multiply(2, 5), 6), const_2), 6))
