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.

4 and 40 8 and 20

The GCF of 5 and 8 is 1. The LCM is 40.

Product = LCM x GCF = 384, sum = 40. Factors of 384 = 2 x 192, 3 x 128, 4 x 96, 6 x 64, 8 x 48, 12 x 34, 16 x 24 That'll do! The numbers are 16 and 24

8 and 80, respectively.
