Number puzzle
"The sum of two positive integers is 216. The greatest common factor of the two numbers is 24. What are all the possible pairs of numbers?"
What approach seems the easiest here?
I can see using solution methods such as:
- algebra
- guess and check
- organized list
- visual representation
Which (or which other) method rings true for you? Which of the two sentences eliminates the most numbers?
