It is known that the greatest common factor of a and B is 60, the least common multiple is 720, and one of them is 180. What is the difference between the two numbers Ladies and gentlemen,

The other number is: 720 △ 60 × (180 △ 60)] × 60 = 240
The difference between the two numbers is: 240-180 = 60
Comprehensive formula: 720 △ 60 × (180 △ 60)] × 60-180 = 60
