It is known that the difference between two natural numbers is 2, and the difference between their least common multiple and greatest common divisor is 142
Let one of the natural numbers be x, and the other bit x + 2, (1) when (x, x + 2) = 1, [x, x + 2] = 142 + 1 = 143, and (x, x + 2) × [x, x + 2] = 1 × 143 = 11 × 13 = x × (x + 2), so x = 11, x + 2 = 13; (2) when (x, x + 2) = 2, [x, x + 2] = 142 + 2 = 144, and (x, x + 2) × [...]
