Let the two numbers be x and y. Let suppose that the average of two numbers is 20. Then,x + y = 40 and 40/GCF = 5, where GCF = 40/5 = 8Since LCM is 48 and GCF is 8, the numbers are 16 and 24, whose average is 20 is true.
The LCM of the given two numbers is 4080
The sum of two numbers is those two numbers multiplied together. For instance, the sum of 4 and 5 is 20.
20 and 100.GCF is 20, and LCM is 100.
1 and 20.
