The GCF of 6 and 10 is 2.
The sum of the first 200 even numbers is 40,200.
16 and 24
16 and 12 how did you get it
The numbers are 34 and 51, which have a sum of 85 and their LCM is 102, the multiple of the highest power of their prime factors 2, 3, 17.
40 and 50
40 and 50
40 and 50
60 and 36
The GCF of 6 and 10 is 2.
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.
The GCF of 9 and 15 is 3. The LCM is 45.
The sum is 335.
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.
The LCM will never be less than the GCF.
