The length, width and height of a rectangular block of wood are just three continuous natural numbers. The volume of the factory building is 504 cubic centimeters. How many square centimeters is the surface area of the rectangular block?

504=9×8×7
The surface area is (9 × 8 + 9 × 7 + 8 × 7) × 2 = 191 × 2 = 382 square centimeters

The product of two natural numbers is 36, and the least common multiple is 120
Elder brother and elder sister, please!

It's impossible
Because when two numbers are coprime, the least common multiple is the product of two numbers
But 36 = 1 × 36
So the biggest is 36
