The GCF of 6 and 10 is 2.

60 and 36

They are: GCF = 5 and LCM = 325 and the sum is 5+325 = 330

You cannot. LCM{2,6,12} = 12 and GCF{2,6,12} = 2 LCM{4,6,12} = 12 and GCF{4,6,12} = 2 The two sets have the same LCM and GCF but, clearly, their sums are different.

How about: 12, 16 and 24

This doesn't work. The LCM of a pair of numbers has to be equal to or larger than the largest number of the pair. If one of the numbers is 60, the other is 120. 60 and 120 have a GCF of 60, not an LCM.

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 GCF of 9 and 15 is 3. The LCM is 45.

The sum is 335.

They are 2, 4 and 10.

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

The LCM will never be less than the GCF.

The sum of the first 200 natural numbers is 20,001.

14 and 21 have a sum of 35 and an LCM of 42

Given any set of numbers, there is only one GCF for them. The sum of that single number will be itself so there is really not much to the sum: it is the GCF.

The sum of all the numbers from 101 through 200 is 15,050.

The sum of all the numbers 1 through 200 is 20,100.

201

16 and 12 how did you get it

The sum of 2 to 200 = 10,100

The sum of all even numbers from 2 through 200 is 40,200.

The sum of the first 200 even numbers is 40,200.
