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.
15 and 25
50 and 45
The GCF is 1.
45 and 10
You need at least two numbers to find a GCF. If that's 4 and 5, the GCF of any two consecutive numbers is 1.
As a general principle, you can find the LCM of two numbers by dividing their product by their GCF. This one won't work. The product of any two numbers with 5 as a common factor would have to end in 5 or 0.
The greatest common factor of the two numbers is 5. 55/5 = 11, 20/5 = 4.
You need at least two numbers to find a GCF. If that's 200 and 205, the GCF is 5.
