what is the least value of x . so that 30 x 55 is divisible by 3 ?
"the sum of the digits of the number is divisible by 3 , then the number is divisible by 3 . 3 + 0 + x + 5 + 5 = 13 + x least value of x may be 2 therefore 13 + 2 = 15 is divisible by 3 . d"
divide(divide(divide(lcm(30, 55), 55), const_4), const_4)
