4 and 40 8 and 20
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.
40 and 50
40 and 50
You need at least two numbers to find either of those.
The GCF of 5 and 8 is 1. The LCM is 40.
