30 and 60
To find the least common multiple (LCM) of two numbers, we first need to find the numbers themselves. Let's call the numbers x and x-7, where one number is 7 less than the other. The LCM of 60 and x is 60x divided by their greatest common divisor (GCD). Since 60 is a multiple of 60 and x is a multiple of x, the LCM is 60x. Therefore, the numbers are 60 and 53.
