Question

The LCM of these three numbers is 60. The GCF is 1. If you add the numbers, the sum is 15. Select the three numbers from the following options: 2, 6, 5, 8, 4 Show your work!

Answer 1

All three numbers must be factors of 60; 8 is not a factor of 60 so it can be excluded.

The numbers left are 2, 4, 5, 6

You must take the three greatest to get a sum of 15: 4+5+6 = 15

and 60 is the GCF of 4, 5, 6
