gcf (greatest common factor) is usually calculated for two (or more) numbers, not for a single number.
How about 16 and 24
16 and 24
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 pair of numbers 16 and 160 has a GCF of 16 and an LCM of 160.
