In mathematics, the Least Common Multiple (LCM) is the smallest positive integer that is divisible by two or more given numbers. For the equation LCM(x * 40) = 1400, it can be found that the odd natural number X is 35. By substituting X = 35 into the equation, we find that the LCM(35 * 40) is equal to 1400, satisfying the given condition.
